Analysis of related properties of flame retardant engineering plastics

More and more engineering plastics are gradually replacing metal, glass and ceramics in automobiles, airplanes, electronics and other industries. For materials exposed to high temperatures, their flame retardancy has become increasingly important.

With the continuous advancement of polymer synthesis and processing technology, engineering plastics have penetrated into various fields of production and life. In many applications, the flame retardancy of plastics is an important performance indicator for the application of materials, and some plastic additives, such as halogen-containing flame retardants, may have potential hazards to the environment and human health due to {TodayHot}. Therefore, in order to solve this contradiction, some users of engineering plastics have abandoned the application of these plastic additives and switched to engineering plastics that have flame retardant properties themselves.

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. These polymers mainly include: polyetheretherketone (PEEK), polyetherimide (PEI), polyphenylene sulfide (PPS), polyphenylsulfone (PPSU), polyethersulfone (PES), polyvinylidene 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.
