Advancements in denier polypropylene fiber, which has in-built flame retardant properties, have created significant interest among various end-user industries such as packaging, construction, aerospace& aircraft, electrical &electronics, and automotive. Currently, there are two methods that are popular in the flame retardant polypropylene market: halogenated and non-halogenated. Both these methods have been effective in imparting flame retardant properties to polypropylene polymer; however, non-halogenated flame retardants are preferred to halogenated flame retardants. Halogenated flame retardants use bromine and chlorine chemicals for fire safety purposes. However, increasing consumer awareness regarding environmental safety and rising number of government regulations on low smoke flame retardant polymers have hampered the usage of halogen flame retardant polypropylene. Therefore, the use of halogenated (brominated and chlorinated) flame retardant polypropylene has been waning in the flame retardant polypropylene market. Non-halogenated(halogen free)flame retardants include alumina trihydrate (ATH), magnesium hydroxide (MDH), nitrogen, antimony trioxide, and phosphorous-based flame retardant polypropylene.
