Analysis on the market development trend of flame retardant engineering plastics

coating engineering plastics are widely used in the construction industry, so flame retardants have become essential additives. However, at present, halogen-containing flame retardants in the market are more harmful to the environment and human health because they have {todayhot} potential hazards. Therefore, in order to solve this contradiction, some users of engineering plastics have abandoned the application of these plastic additives, Instead, choose engineering plastics that have flame retardant properties by themselves

flame retardant polymers mainly include polyether ether ketone (PEEK), polyether imide (PEI), polyphenylene sulfide (PPS), polyphenylsulfone (PPSU), polyether sulfone (PES), polyvinylidene fluoride (PVDF) and liquid crystal polymer (LCP). Other polymers such as PVC and modified polyphenylene oxide (PPO) have certain flame retardancy, but a certain amount of additives need to be added to enhance this performance

pei is an amorphous polymer. The continuous use temperature of negotiator reaches 180 ℃, which is a major breakthrough in the research and development project of copper alloy new materials with high thermal conductivity in early June this year. Hydrocarbons, halogenated solvents, water and automotive liquids have strong resistance, and their glass transition temperature is 217 ℃. According to the data provided by Pei supplier Ge, the combustion rate of 0.25mm spline flame is detected as V-0 by UL94, and has low smoke emission, can withstand a variety of chemicals, and has high strength, modulus and high temperature creep resistance. Pei resins are available in non reinforced and reinforced grades. Typical fillers are carbon fiber, glass fiber and some minerals

in the manufacturing of auto parts, Pei can replace metal to manufacture dampers, sensors, air conditioners, plastic Q & A ignition systems, taking into account the impact of tidal impact on parts and transmission system accessories. Pei's flame retardancy, low smoke and low toxic gas emissions also make this material used in aerospace, such as gas and fuel valves, steering wheels, interior decorative surfaces, food trays, etc. Electronic lighting components such as connectors and reflectors made of Pei materials are also used to give full play to the flame retardant advantages of the polymer. In addition, Pei can be processed by standard injection molding processing methods, and the wall thickness of the parts can reach 0.25mm Pei should be dried at 140 ℃ ~150 ℃ for several hours before processing

polymers with flame retardancy usually have other excellent properties, such as strength, dimensional stability, chemical resistance and wear resistance, but these materials are usually more expensive than those without flame retardancy. However, in applications requiring high performance and high flame retardancy, these resins are needed to expand their capabilities
