Flame retardancy of modified plastics

Modified plastics flame retardant technology, currently mainly additive brominated flame retardants, commonly used are decabromodiphenyl ether, octabromoether, tetrabromobisphenol A, hexabromocyclododecane, especially the use of decabromodiphenyl is large, brominated epoxy resin because of its excellent melting rate, high flame retardant efficiency, excellent thermal stability. It is widely used in PBT, PET, ABS, nylon 66 and other engineering plastics. Thermoplastic is used in the flame retardant treatment of PC / ABS plastic alloy.

Blending of modified plastics and plastic alloy technology
Other types of flame retardants in the family are phosphorus, triazine, silicon, shrinkage, inorganic, etc. These flame retardants play a common flame retardant effect in various application areas. In phosphorus flame retardants, the types of organic phosphorus are mostly oil liquids, which are not easy to add in the process of polymer processing. They are commonly used in polyurethane foam, transformer oil, cellulose resin, natural and synthetic rubber. The red phosphorus in the inorganic phosphorus system is a pure flame retardant element with good flame retardant effect, but it has bright color, so its application is limited locally. The application of red phosphorus should pay attention to micronization and surface coating, so that it has better dispersion in polymer, good compatibility with polymer, not easy to migrate, and can persist in the flame retardant properties of polymer.
