Flame Retardants Exolit OP1400

Exolit OP1400 is actually the leader of industrial flame retardants today, and is widely used in flame retardant modification of materials such as polyolefins and engineering plastics. Its main chemical composition is ammonium polyphosphate (APP). Ammonium polyphosphate, the chemical formula is commonly (NH-PO-3) _n, is a long chain structure, white powder, insoluble in water, and has high thermal stability. In high temperature environments, APP can release phosphoric acid, which helps to form a carbonized layer, form an isolation layer, cut off oxygen, and inhibit the spread of fire. It is an excellent intumescent flame retardant. Considering its properties, APP is odorless and tasteless, with a high ignition point. Ammonium tripolyphosphate and phosphorus pentoxide are precipitated during decomposition, which can cooperate with polymer materials and expand rapidly in the early stage of combustion to form a porous carbon shell, blocking the flame source. Its chemical properties are mild, and it has the virtue of environmental protection. It does not contain halogens. It does not produce harmful gases during incineration. It is in line with the concept of green cycle, especially in Europe, America and other countries. OP1400 series is prepared based on a high degree of polymerization APP. The degree of polymerization is generally higher than one thousand, there are very few impurities, and the thermal decomposition temperature can reach more than 275 degrees Celsius. Its powder particle size can be surface treated, and the dispersion and compatibility can be improved, which is convenient for compounding with different resins. Today, it is used in polyolefin, EVA, PU foam, epoxy resin and other systems, especially to maintain mechanical properties, giving the product good flame retardancy and low smoke emissions. In summary, the main ingredient of Exolit OP1400 is ammonium polyphosphate, which is stable and easy to use, and has outstanding flame retardant effect. Its use of modern formulations and processes not only ensures environmental protection properties, but also practical value, and is widely adopted by the industry. This is the essence of the equivalent substance of Exolit OP1400.

Its application fields are very wide, especially in electronics, building materials, transportation, etc. The common uses are as follows: In the electrical and electronic industry, Exolit OP1400 or its equivalents are always additives for epoxy resins, polycarbonates, thermoplastic polyurethane and other materials. It is used in the manufacture of printed circuit boards, connectors, sockets and switches, etc., which can not only improve the flame retardancy of products, but also do not damage their electrical properties. Due to its halogen-free environmental protection, it is suitable for the restrictions of European Union RoHS, REACH and other regulations, so it is particularly favored for high-end electronic equipment. In construction materials, such flame retardants are often mixed with glass fiber reinforced plastics, polypropylene, polyamide and unsaturated polyester, etc. They are applied to wall panels, ceilings, pipes and floors. It can prevent the spread of fire, reduce the escape of harmful smoke and toxic gases, and ensure the safety of the residence. In addition, in transportation equipment, such as automobiles, rail vehicles, aircraft and ships, etc., flame retardants equivalent to Exolit OP1400 are also frequently used for interior parts, instrument panels, line coverings, etc. Transportation is related to people's lives, and fire safety is of paramount importance. Suitable for halogen-free phosphorus-based flame retardants, not only the parts made have excellent flame retardant and low smoke and low toxicity characteristics, but also have excellent mechanical properties, which are emphasized by the industry. There are also communications, home appliances and other fields, where plastic parts need to be both environmentally friendly and flame retardant, there is a place for this agent. Exolit OP1400 and its equivalent flame retardants are widely used in many aspects of contemporary polymer industry because of their high efficiency and environmental protection, adapt to the needs of the times. In summary, halogen-free environmental protection and flame retardant are the general trend. Exolit OP1400's common application field has a wide range and broad prospects. It is also the leader of today's materials.

Exolit OP1400, from a famous European factory, is the leader of flame retardants today, and its flame retardant performance is highly praised. If its performance is equivalent, the chemical nature and practical application effect need to be carefully examined. OP1400 is mainly made of organophosphate, which is an intumescent flame retardant. It is often used in polypropylene and other polymer materials. It can quickly form a carbon layer in case of fire, isolate oxygen and inhibit combustion. Its excellent performance and environmental protection advantages are widely used in electronic appliances, rail transit, building decoration and other fields. Test its flame retardant performance, and the balance is mainly based on oxygen index, UL94 grade, and thermal stability. The oxygen index of OP1400 can reach more than 28%, surpassing ordinary flame retardants. Its products are halogen-free, benzene-free, and have no dripping phenomenon. When burned, the amount of smoke is low and the toxicity is also low. With suitable carriers and processing technologies, it can reach UL94 V-0 grade. The thermal stability is also very ideal, suitable for a variety of processing conditions, can withstand higher temperatures without decomposition, and the combustion residual carbon layer is solid, protecting the substrate from flame erosion. If you find its equivalent, you can pay attention to Clariant Exolit OP1314, or Italmatch P 422, or Nabaltec MH series. Such flame retardants are also mainly phosphorus-based, and have the characteristics of high efficiency, halogen-free and environmental protection. Its flame retardant effect in polypropylene composites is almost the same. The commonality of organophosphorus-based flame retardants is that they expand and foam, expand rapidly in case of fire, block heat and air, and inhibit the spread of fire. Practical tests show that the equivalent product can also reach an oxygen index of 28-32%, and the combustion grade is generally UL94 V-0. Less smoke generation, suitable for green manufacturing and high-end markets. Overall, Exolit OP1400 is unique in flame retardant performance. There are equivalent flame retardants on the market that match it, and it can be applied to similar high-demand environments. Its performance is known for its high efficiency, stability and environmental protection, and it is a model of modern flame retardant technology. When choosing an equivalent, the flame retardant grade, thermal stability, compatibility and environmental protection standards should be taken as the key to keep pace with OP1400.

After adding Exolit OP1400, the mechanical properties of the material are less affected, and a good balance can be achieved between flame retardancy and mechanical properties. At the conventional addition ratio (15%-25%), the impact on the key mechanical properties of substrates such as polyamide is controllable. Taking reinforced PA66 as an example, after adding 20% Exolit OP1400, the tensile strength usually decreases by no more than 10%, and the impact strength retention rate can reach more than 80%, which can still meet the structural requirements of components such as electrical connectors. For non-reinforced PA materials, the flexural modulus is slightly reduced, but it is sufficient to maintain the dimensional stability of injection molded parts. In terms of high-temperature mechanical properties, the high thermal stability of Exolit OP1400 makes the material's creep resistance at 120-150℃ only slightly reduced, making it suitable for high-temperature environment components such as automotive engine compartments. However, when the addition amount exceeds 30%, some materials may become more brittle, which needs to be alleviated by compounding with reinforcing agents such as glass fiber. In practical applications, changes in mechanical properties are closely related to the type of substrate and processing technology. It is recommended to further reduce the impact through formula optimization (such as adding a small amount of toughening agent). Ultimately, the optimal addition ratio needs to be determined through experiments based on the mechanical index requirements of specific products.

Exolit OP1400 is a modern and efficient organophosphine-based flame retardant. It is mostly used in thermoplastics and thermosetting resins. Its properties are stable, environmentally friendly and halogen-free, and it is widely respected in the field of engineering plastics. If its equivalent is found, it is the high-efficiency grade product of ammonium polyphosphate (APP). However, the typical dosage, the substrate and performance requirements must be considered. Where used in thermoplastic resins such as polypropylene (PP) and polyethylene (PE), the commonly used amount is 18% to 25% per 100 parts of resin, mostly based on the base mass ratio. If added to epoxy resins or unsaturated polyesters, the usual dosage is about 25% to 30%, and the upper can reach 35%. The above are the main points of the three effects of carbon formation, smoke suppression and flame retardancy. As for the way it is added, it is best to re-mix the cover. When working, it is appropriate to take the premixing method. First, the OP1400 and the main resin, plasticizer and required additives are fully stirred in a high-speed mixer in proportion to make it evenly dispersed, and then melted and blended in a twin-screw extruder, so that the fine distribution of particles can be maintained and the agglomeration phenomenon can be reduced. The molding process can also be injection molding, extrusion or calendering methods, provided that the processing temperature does not exceed 260 degrees Celsius to prevent thermal decomposition and affect the appearance and performance of the product. There is still the cooperation of additives, which can improve the flame retardant characteristics. In case of carbon synergist (such as pentaerythritol, melamine, etc.), the two are used together, and the amount added is fine-tuned according to the use. It can also reduce the dosage of OP1400 itself and enhance the flame retardant grade, so as to obtain a rating above UL94 V-0. Sometimes it is necessary to take into account the mechanical properties and weather resistance requirements of the product. Tougheners, stabilizers, etc. can be added to make both flame retardant and physical properties. In short, the addition of OP1400 and its equivalents must adhere to the "appropriate amount is expensive", which will not weaken the material properties too much, and will not be slightly difficult to meet the standard. With various additives and sophisticated mixing processes, it can achieve high-efficiency flame retardant and high-quality effects.
