Paint engineering plastics are widely used in the construction industry, so flame retardants have become an indispensable additive, but currently, halogen-containing flame retardants on the market are potentially harmful to the environment and human health, so To solve this contradiction, some users of engineering plastics have abandoned the application of these plastic additives and switched to engineering plastics that have their own flame retardant properties. Flame retardant polymers mainly include: polyetheretherketone (PEEK), polyetherimide (PEI), polyphenylene sulfide (PPS), polyphenylsulfone (PPSU), polyethersulfone (PES), and polydisperse. Vinyl fluoride (PVDF) and liquid crystal polymer (LCP). Other polymers such as PVC, modified polyphenylene ether (PPO), etc. have some flame retardancy, but require a certain amount of additives to enhance this performance. PEI is an amorphous polymer with a continuous use temperature of 180 ° C. It is highly resistant to hydrocarbons, halogenated solvents, water and automotive liquids with a glass transition temperature of 217 ° C. According to the data provided by PEI supplier GE, the 0.25mm spline flame burning rate is V-0 rated by UL94, and it 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 both non-enhanced and enhanced grades. Typical fillers are carbon fiber, fiberglass and certain minerals. In the manufacture of automotive parts, PEI can replace metal manufacturing dampers, sensors, air conditioners, ignition system components and drivetrain accessories. PEI's flame retardancy and low smoke and low toxic gas emissions also make this material suitable for use on aerospace vehicles such as gas and fuel valves, steering wheels, interior finish surfaces, food trays, and more. Electronic lighting components such as connectors and mirrors made of PEI materials are also used to take advantage of the flame retardancy of the polymer. In addition, PEI can be processed by standard injection molding methods, and the resulting part can have a wall thickness of 0.25 mm. Before processing, PEI should be dried at 140 ° C ~ 150 ° C for several hours. Flame retardant polymers generally also have other excellent properties such as strength, dimensional stability, chemical resistance and abrasion resistance, etc., but these materials are generally more expensive than those that do not have flame retardancy, however These resins are needed to be used in applications where high performance and high flame retardancy are required.
