GY-FR-TPEE Non-halogen TPEE（Hytrel）Flame Retardant

Description

Intro

TPEE（Thermoplastic Polyester Elastomer）is a block polymer which contains polyester hard segment and polyether soft segment. Polyether soft segment and non-crystalline polyester formation of amorphous polyester hard segment crystalline into micro region which make physical cross-linking point. TPEE is manufactured 1,4-butanediol (1,4-Butylene glycol) and poly-butylene glycol (Polytetra-methylene glycol) and terephthalate (DMT) or terephthalic acid (PTA) for the condensation-copolymerization，and it is made by thermoplastic polyester elastomer composites via kneading program.
Due to shortcoming for the structure of TPEE is flammable, especially the limited use for the ingredients of polyester and polyether soft segment and alcohols and esters of TPEE.  Therefore, GYC technology department developed environmental friendly flame retardant GY-FR-TPEE for TPEE. When the GY-FR-TPEE added to TPEE, it will have fire retardant effect for rubber elasticity and the strength of fire retardant engineering plastics; Soft segment gives it elasticity fireproof structure, so there is resistance rubber TPEE all properties; Hard segment given Its processing performance, so there TPEE plastic fire performance; and rubber, it has a better processing performance and longer service life and fire protection; and engineering plastics compared to the same high fire intensity features, and flexibility and dynamic mechanical properties better. GY-FR-TPEE enhances the added value of TPEE, and makes it have more superior fire properties. TPEE with flame retardant widely used in fire retardant wire and fiber coated housing and a variety of flameproof electrical appliances and automotive parts.
