What are the main ingredients of Flame Retardant MC25?
Flame Retardant MC25 is a chemical product, which is widely used in plastics, rubber and other materials to increase its flame retardancy. Its main components are organic compounds of elements such as phosphorus and nitrogen. Now briefly describe its components and functions as follows:
MC25 is a phosphonate flame retardant, rich in phosphorus, which can release phosphoric acids when heated, and can form a coking layer in case of fire. A dense carbonized film is formed on the surface of the material. This film can inhibit the infiltration of oxygen, inhibit the decomposition of combustibles, and reduce the rate of flame spread. It also contains organic nitrogen components, which can release inert gases such as ammonia at high temperatures, dilute oxygen in the air, and cut off combustion conditions. Phosphorus and nitrogen work together to form a more significant flame retardant effect. In addition, some products or a small amount of inorganic fillers such as alumina, magnesium hydroxide, etc., increase their thermal stability and mechanical strength.
MC25 does not contain halogens, which is more environmentally friendly than traditional halogen flame retardants; it is not easy to precipitate harmful gases during combustion, and is widely respected. Its composition and structure are complex. Although it is mainly phosphonate, it is often accompanied by capacitors, dispersants and trace additives to help it distribute in the substrate, improve processing performance and finished product homogeneity. Its preparation requires precise temperature and pressure control, and strict reaction conditions to form high-quality products.
It is also pointed out that phosphorus and nitrogen are flame retardant, and have both smoke suppression and non-toxicity. Used in the fields of electronic appliances, building materials, automotive parts, etc., it not only ensures safety, but also complies with today's environmental regulations, and is valued by the polymer materials industry. In a nutshell, the main component of MC25 is organophosphonate compound phosphorus and nitrogen, supplemented by trace inorganic fillers. Its mechanism of action lies in the synergistic flame retardancy of the gas phase and the condensed phase, carbonization of the protective body, gas release and oxygen reduction, and the achievement of excellent flame retardant performance.
To be said, MC25 takes phosphorus and nitrogen organic compounds as the main purpose and cooperates with a variety of additives to exert fire protection in polymer materials, which is widely known in the world.
What materials is Flame Retardant MC25 suitable for?
Flame Retardant MC25 is a new innovation in contemporary chemical technology, with warm and effective performance. Considering its application, it is suitable for a variety of polymer materials. Such as polyolefins, polyethylene, polypropylene, polystyrene, ABS resin, polyester, polyurethane, etc., can benefit from its flame retardant power. It is especially important for its application in the industry.
Such as polyethylene and polypropylene, they are flammable in nature and spread rapidly in case of fire. And MC25 penetrates into them, which can change its thermal decomposition mechanism, increase the ignition point of substances, reduce smoke and dust, reduce flame propagation, and make it safer. As for polystyrene and ABS resins, they are all commonly used engineering plastics, which are widely used in home appliances, automobiles, electronics and other fields. When MC25 is integrated into it, a carbonized layer can be formed on the surface of its products in case of fire, which is strong and non-flammable, maintaining the integrity of its structure. If polyester, polyurethane, or as fiber, or as foam, it is commonly used in home furnishings and building materials. If there is no flame retardant, it will be difficult to resist fire. The application of MC25 can make it foam evenly, and it has both flexibility and flame retardant functions.
MC25 not only acts on the thermoplastic, but also is compatible with a few thermosetting plastics. Applied to epoxy resins, phenolic resins, or electrical insulation, or copper clad laminate materials, it can improve the flame retardant level and ensure safety. So many materials are compatible, which is really relied on by the industry. In addition to its superior performance, MC25 can also be shared with other additives, such as plasticizers, antioxidants, etc., which do not conflict with each other, have stable compositions, and do not damage the original properties of the product.
From this perspective, MC25 adapts to a wide range of materials, whether it is industrial manufacturing, civil products, or even high-end technology. The MC25 can respond to the needs of flame retardancy, not only to improve product safety, but also to promote the goal of green environmental protection. With the prosperity of technology and the variety of materials, MC25 can be described as an indispensable product in the modern flame retardant system.
What is the amount of Flame Retardant MC25 generally added?
Flame Retardant MC25 is a new type of flame retardant, which is widely used in the modification of polymer materials. If you ask about its addition amount, it depends on the type of material and performance requirements. MC25 is stable and compatible with a variety of resins, and can be used for polyethylene, polypropylene, ABS, polyurethane, etc. If you pursue a general level of flame retardant effect, the common addition amount is between 10% and 15%, which is the middle of the trade-off between material performance, cost and flame retardant effect. If you need a high flame retardant grade, such as UL94 V-0 standard, the addition amount is often increased to more than 18% to 20%.
Although flame retardants can effectively inhibit combustion, their interaction with resins more or less affects the mechanical properties and processability of products, especially the high addition amount. Therefore, when designing the formula, it is necessary to take into account the flame retardant and mechanical properties, and should be carefully considered through experiments. During the addition process, it should be fully dispersed to avoid agglomeration, so as to obtain the best material properties.
In case of special application environments, such as high temperature and high hydrolysis resistance requirements, the addition amount needs to be more finely prepared. Sometimes, MC25 is also used in combination with other flame retardants to achieve synergistic enhancement effect, but the total dosage should also be controlled so as not to damage the material properties. For example, cables, electronic component shells, high flame retardant requirements often make the dosage of MC25 tend to be high, while daily necessities, furniture, etc. can be slightly reduced, taking into account economy.
In summary, the recommended addition amount of MC25 is usually between 10 and 20 percent. The level depends on the type of base material, end use, target flame retardant grade, and other performance trade-offs. When selecting, check the material characteristics carefully, refer to the product description and relevant test data, in order to ensure the best flame retardant and comprehensive performance. If there are no special requirements, it is appropriate to adopt the manufacturer's suggestion first, and then fine-tune it to achieve the most suitable compatibility.
What are the storage requirements for the Flame Retardant MC25?
Answer:
Flame Retardant MC25 is a flame retardant used in today's industry. Its properties are volatile, volatile in case of moisture, and its efficacy will be reduced in case of high temperature or strong sun. It is stored with strong oxidants or strong acids, and it is afraid of chemical reactions, resulting in hidden dangers. It is advisable to choose a clean, dry and cool storage place. The storage room must be well ventilated, protected from wind and rain leakage, and should not be exposed to sunlight. Its temperature should be maintained within normal temperature, not too high, and should not drop abruptly. Indoor humidity should also be controlled to prevent its clumping and mutation, and mildew and moth prevention should be given priority; it should be stored in a closed container, metal and plastic can be used, but materials that do not react with it must be selected to protect its purity.
When placing, do not store with flammable and explosive materials; keep away from fire sources, oil and reducing agents should not be near each other; arrange in an orderly manner and mark clearly, which is convenient for inspection and verification. After unsealing, it should be used up quickly. If it is not exhausted, it must be re-sealed and tightened to prevent long-term deterioration. If moving and handling, it must be gently lifted and stably placed to prevent external force from hitting and leaking; or during storage, regular inspections and inspections should be made. If there is any abnormality, it should be properly disposed of immediately to prevent hidden dangers from breeding.
In addition, protective warnings need to be set up to strictly prohibit fireworks. If the protective facilities are not good, it is very easy to cause disasters. The storage place should be away from drinking water sources, rivers, etc.; the storage amount should be measured according to one's capacity, so as not to overload the storage. All disposal should be carried out in accordance with the rules and regulations to maintain its stability. All these storage methods are to ensure their effectiveness and safety.
What environmental or safety standards does the Flame Retardant MC25 meet?
Flame Retardant MC25 is a new material today. It is widely used in many industrial products. Its properties are stable and environmentally friendly. In terms of its environmental protection and safety standards, it is really high in the world. First look at the European Union's RoHS (Restriction of Hazardous Substances) Directive, which prohibits lead, cadmium, mercury, hexavalent chromium and certain brominated flame retardants. MC25 does not contain the above harmful elements, so its products can be safely circulated in Europa. Looking at the REACH regulation, which focuses on the control of substances of very high concern (SVHC), MC25 has been tested and certified, and it is not particularly listed. It is in line with the system of the European Union.
Take a look at the UL 94 flame retardant test in North America, such as V-0 grade, MC25 can pass the strict assessment of short flame, no residual drops, incineration of non-toxic smoke, etc., and then obtain UL certification. There is also California Decree 65 (Proposition 65), which specializes in the notification of carcinogenic and reproductive hazards. The ingredients contained in MC25 do not violate this law, and they are also safe for circulation in North America. In Asia, the GB/T 24001 environmental management system and GB/T 28001 occupational health and safety management system of China, the production process of MC25 has been inspected by a third-party organization, and the certificates are complete to ensure that the production and application are harmless to humans and animals.
In terms of environmental protection, MC25 does not contain persistent organic pollutants such as polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE), which meets the requirements of the Stockholm Convention. Its degradation by-products have no acute toxicity and do not pollute water and soil. As for safety, MC25 does not release a lot of smoke and irritating gases when burned, ensuring the safety of workers during operation and external use. Many large end point manufacturers choose this material, and they must check the MSDS (material safety data table) one by one. MC25 is detailed in the hazard classification and exposure limit tables, which is convenient for all parties to apply in compliance.
Overall, MC25 meets the European Union RoHS, REACH, American UL 94, California 65, and China's two major management systems and global POPs conventions. Its performance is safe, especially green and environmentally friendly. Businesses and consumers can use it without worry, and it is the best among flame retardant additives.
