Historical Development
In the past, the craftsmanship was not yet perfected. Although nylon and glass fiber (PA-GF) had high strength, it was flammable in case of fire, and the safety was not guaranteed. Later craftsmen studied the technique of preventing flames, and first added halogen compounds. Although it was possible to curb fire, it was poisonous to smoke, and the environment was at risk. The technology is new today, and many wise men have worked together to develop and refine, thus creating an economical flame retardant, which is not only beneficial to production, but also benefits the ecology. Its ratio is exquisite, it can suppress the spread of fire, and it is no longer harmful to halogens. It is widely used in electromechanical, automotive and other fields. However, the product has undergone formula revolution and process refinement since its inception to its peak, and has achieved today's high efficiency and stability.

Preparation Method
Take phosphate, nitrogen-based compounds and inorganic fillers as raw materials, mix and grind according to a certain proportion. Set in a reaction kettle, pass an appropriate amount of solvent, slowly add stirring, and heat up to a predetermined reaction temperature at medium temperature. At first, phosphate and nitrogen-based compounds form a synergist, which is introduced by a catalyst to promote chemical bonding reaction, cross-linking of chain segments, and dense structure. In the reaction, additives are added to enhance the compatibility with PA and GF. After some time, the reaction is completed, centrifuged and filtered, washed to remove impurities, and the preliminary product is obtained; followed by drying, the powder particles are uniform. The catalytic mechanism is Lewis acid or metal salt to activate the reaction check point, reduce the energy barrier, make the functional groups easy to cross-link, and enhance the stability of the flame retardant system. The obtained flame retardant is used in combination with polyamide and glass fiber, which is economical and has excellent performance.
Chemical Reactions & Modifications
Polyamide glass fiber composites are strong and flammable, so they need flame retardant modification, which should meet the needs of industry. Today, there is an economical flame retardant applied to PA-GF. The method is mainly phosphine compounds, nitrogen series, etc., or in coordination with melamine salts, uniformly dispersed in the matrix. When heated, it decomposes and releases non-flammable gases, inhibits oxidation reactions, or forms carbonaceous isolation layers, which weakens combustion spread. During the modification process, through surface treatment, reactive grafting and other chemical methods, the flame retardant and polyamide chains produce good interface synergy without damaging mechanical properties. Its chemical reaction, or esterification, amination, etc., makes the active group firmly attached to the main chain, which not only enhances the flame retardant efficiency, but also maintains the strength of the material. Therefore, the combination of flame retardant and modification is cost-controllable, making it a practical choice.

The high-grade flame retardant is used in polyamide glass-reinforced materials (PA-GF) to improve the self-extinguishing ability of materials in case of fire, prevent the spread of fire, and ensure the safety of utensils. In today's industry, PA-GF and flame retardant materials are mostly used for engine parts, components, and external components of automobile manufacturing. Due to the good resistance of PA itself, the low-grade glass is increased, and the mechanical resistance is greater. However, the flame retardant performance is still insufficient, so it must be used to increase its safety. The low-grade flame retardant is low-cost, convenient, and effective. It can be used in a large number of products without greatly increasing the cost.
Its main uses are four: one.
Nowadays, flame retardant PA-GF is used in household appliances, electrical appliances, sockets, distribution boxes, etc., to prevent fire. Second, steam engineering. Bundle brackets, engine parts, air pumps, etc., are often used in high-altitude environments, which require flame retardant and anti-fire. Therefore, it is often used in high-grade flame retardant PA-GF. Three building materials. It is used in room distribution pipes, fire protection fittings, etc., which are safe and durable. Four household appliances. External parts of refrigerators, laundry, microwaves, etc., are commonly used for this material, which is both solid and flame-resistant, in line with industry standards.

What is the effect of Economic Flame Retardant for PA-GF on the mechanical properties of glass fiber reinforced nylon?
Economical flame retardants are used in glass fiber reinforced nylon (PA-GF), which has a significant impact on its mechanical properties. Examine the reason, because flame retardants are mostly added to the matrix in the form of additives to change the microstructure and mechanical properties of the original material. PA is tough in nature, reinforced with glass fiber, and has both high strength and excellent heat resistance. If blended with economical flame retardants, although it can give the material the ability to resist incineration, it cannot ignore the loss of mechanical properties.
Flame retardants are mostly inorganic or organic compounds. In the dopant, the filling phase interface increases, which increases the micropores of the originally dense matrix, loosens the structure, and weakens the tensile strength and impact toughness. And the compatibility of flame retardants with glass fiber and nylon matrix is limited, the interfacial bonding force is reduced, and the fiber reinforcement effect is also weakened. Especially economical flame retardants have coarser particle size and uneven dispersion, the force point is uneven, the prone stress is concentrated, and the impact performance is the first to bear the brunt.
The degree of performance loss is closely related to the type of flame retardant, the amount added and the uniformity of dispersion. If the dosage is moderate and finely dispersed by surface modification or compounding process, the negative impact on mechanical properties can be slightly reduced. For example, phosphorus and nitrogen series environmentally friendly flame retardants have fine particles and are easier to blend with the matrix. Although the strength is slightly reduced, they can still maintain practical standards.
However, economical flame retardants are mostly cost-first, and the particle size and dispersibility are difficult to compare with high-end products. The common tensile strength decreases by 10-30%, and the impact performance decreases even more. If it is a high-filling system, the brittleness is particularly increased, and the material is prone to fracture under load or impact. If combined with reasonable processing, some of its disadvantages can be compensated by additives.
In general, although economical flame retardants can improve the flame retardant grade of PA-GF, they have a certain weakening of mechanical properties. Practical application requires a trade-off between flame retardant and mechanical properties, and the appropriate dosage and category are selected in order to obtain both flame retardant and mechanical properties.

What is the amount of Economic Flame Retardant for PA-GF?
The application of economical flame retardants in nylon glass fiber composites (PA-GF) has its own rules and is not random. Its essence is to improve the flame retardant properties of the material without affecting its mechanical strength, and also take into account cost control. Examine many formulas on the market, the dosage is usually between 10% and 15% of the total formula mass. Or due to different types of flame retardants, the performance is different, and the applicable amount is also different.
Common economical flame retardants such as red phosphorus, antimony trioxide, brominated organic flame retardants, and intumescent flame retardants. Its mechanism of action may inhibit free radical reactions in the gas phase, or form a carbon layer barrier in the condensed phase. Taking red phosphorus as an example, it is mostly added in microcapsules to prevent moisture absorption and improve dispersion. The dosage is mostly about 12%, and the upper and lower can be slightly adjusted according to the formula. Antimony trioxide needs to be used with bromide, usually the bromine content is about 12% -15% in total. If an intumescent flame retardant is used, it can also play a good role between 10% -15% because it is more environmentally friendly, but it needs to take into account the molding fluidity and the appearance of the product.
The addition of flame retardants needs to consider the content of glass fiber. Because glass fiber has certain flame suppression properties, the addition amount can be appropriately adjusted. Ultimately, the UL94 flame retardant grade (such as V0, V1, V2) is used as the assessment standard. If you add too much, the material properties will become brittle, the color will become darker, and the cost will increase; if you add too little, the flame retardant will not meet the standard.
At the beginning of the test, it is recommended to start with a low dose and gradually increase it, observe the changes in flame retardant and mechanical properties, and choose the best ratio. Conventional production mostly follows customer technical specifications, but technological progress may be supplemented by synergistic additives, such as lubricants, antioxidants, and dispersants, to reduce the amount of flame retardants and improve the balance of composite properties.
In summary, the appropriate range for economical flame retardants in PA-GF materials is often 10% -15%, and the actual test results of the formula shall prevail. This is the fusion of technology and science, and it requires detailed consideration by technical personnel to obtain the best results.

Does the Economic Flame Retardant for PA-GF meet environmental and safety standards?
Economical flame retardants are used in PA-GF, and whether they meet environmental protection and safety standards should be discussed from the aspects of raw material source, production process, use performance and impact on the environment and human body.
Flame retardants are often used in synthetic materials to enhance safety and are widely used in the formulation of nylon glass fiber reinforcement (PA-GF). In today's world, the concept of energy conservation and environmental protection is increasingly apparent, and the use of chemical raw materials is increasingly restricted by regulations. When it comes to economical flame retardants, they are mostly phosphorus-based, nitrogen-based or halogen-free organic compounds, and there are few high-polluting substances such as heavy metals and bromine. If international standards such as RoHS and REACH are adopted, economical flame retardants can mostly meet the provisions, and there is no excess of harmful elements.
Energy conservation and emission reduction in chemical production processes are listed as important norms. Advanced manufacturers optimize processes, regulate waste treatment, and reduce the emission of harmful gases and waste liquids; testing systems are also gradually improving to ensure low residue content and reduce environmental risks. Before market circulation, it is verified by third parties that its products do not contain highly toxic substances and do not cause lasting harm to the environment.
However, environmental impact refers to the aging and decomposition during use, or components that may be volatilized during combustion. Economical flame retardants, such as halogen-free materials, decompose and release mostly harmless substances, far exceeding the carcinogenic and allergenic risks of brominated flame retardants. Furthermore, some products can be recycled to reduce the growth of waste and are environmentally friendly.
In terms of safety, economical flame retardants are mostly based on physical barrier and synergistic flame suppression mechanisms, which greatly improve the fire resistance of their products and reduce fire hazards. For human health, except for a very few varieties that may be sensitized, most of them have been verified by safety toxicology and have no significant adverse effects under normal conditions. However, if the operation is improper, direct contact or high temperature decomposition release still needs to be prevented. It is advisable to wear protective gear and have good ventilation.
In general, if the application of economical flame retardants in PA-GF is properly selected and standardized, it can comply with international environmental protection and safety regulations. However, specific products must be carefully screened with reference to test reports and regulations to ensure that nothing goes wrong.

What certification levels can be achieved for the flame retardant effect of the Economic Flame Retardant for PA-GF?
PA-GF is also a polyamide glass fiber reinforced composite material. Today, economical flame retardants are applied to it, hoping to improve its fire resistance. Popular flame retardant grades on the market are UL-94, V0, V1, V2 grades, and others such as GWIT, GWFI and other international certifications. If economical flame retardants are used in PA-GF, the flame retardant grade that can be achieved depends on the nature, dosage, and compatibility process of the flame retardant used.
Economical flame retardants, mostly halogens or phosphorus-containing, and sometimes mineral fillers. If the process is correct, the dosage of 30 to 40 parts can make the PA-GF material often obtain V2 in the UL-94 standard test, and the increment can be increased by V1. When it reaches 50 parts, if the fiber ratio is reasonable and the material is evenly dispersed, it is not impossible to reach the V0 grade. For V0, within ten seconds of two flashes on the standard sample strip, the fire self-extinguishes, and the dripping material must not ignite the cotton, which is the most difficult.
In addition, if the flame retardant is selected from environmentally friendly and high-efficiency categories, although the cost is slightly increased, it is more likely to obtain V0, and environmental standards such as ROHS and REACH are taken into account. If the dose is only reduced for economy, it is only V2. If you meet the technical requirements of the automotive, home appliances, electronics and other industries, you must also pass the glowing wire test (GWIT, GWFI), and the economical flame retardant PA-GF can often reach more than 750 ° C, and some are barely 800 ° C.
European Union EN 60695 and IEC 60695 are the prevailing flame retardant test guidelines. If this test is followed, the economical flame retardant PA-GF can generally meet the application-level requirements. However, in the case of the highest fire protection standards in the railway and aviation fields, such as EN45545 or UL746C, etc., under the guarantee of the best cost performance, the economical flame retardant may not meet all the stringent indicators.
In conclusion, economical flame retardant PA-GF can often be certified UL-94 V2 to V0 grade, and V0 is desirable for higher dosages. GWIT can also reach 750-800 ° C, which is suitable for most industrial fields. If you need a higher fire protection level, it is advisable to take a high-efficiency special flame retardant system or add a synergist. This is a trade-off between economy and flame retardant performance, and it is also a clever place.
Economical flame retardants, mostly halogens or phosphorus-containing, and sometimes mineral fillers. If the process is correct, the dosage of 30 to 40 parts can make the PA-GF material often obtain V2 in the UL-94 standard test, and the increment can be increased by V1. When it reaches 50 parts, if the fiber ratio is reasonable and the material is evenly dispersed, it is not impossible to reach the V0 grade. For V0, within ten seconds of two flashes on the standard sample strip, the fire self-extinguishes, and the dripping material must not ignite the cotton, which is the most difficult.
In addition, if the flame retardant is selected from environmentally friendly and high-efficiency categories, although the cost is slightly increased, it is more likely to obtain V0, and environmental standards such as ROHS and REACH are taken into account. If the dose is only reduced for economy, it is only V2. If you meet the technical requirements of the automotive, home appliances, electronics and other industries, you must also pass the glowing wire test (GWIT, GWFI), and the economical flame retardant PA-GF can often reach more than 750 ° C, and some are barely 800 ° C.
European Union EN 60695 and IEC 60695 are the prevailing flame retardant test guidelines. If this test is followed, the economical flame retardant PA-GF can generally meet the application-level requirements. However, in the case of the highest fire protection standards in the railway and aviation fields, such as EN45545 or UL746C, etc., under the guarantee of the best cost performance, the economical flame retardant may not meet all the stringent indicators.
In conclusion, economical flame retardant PA-GF can often be certified UL-94 V2 to V0 grade, and V0 is desirable for higher dosages. GWIT can also reach 750-800 ° C, which is suitable for most industrial fields. If you need a higher fire protection level, it is advisable to take a high-efficiency special flame retardant system or add a synergist. This is a trade-off between economy and flame retardant performance, and it is also a clever place.
