Polybutylene terephthalate, English polybutylene terephthalate (PBT), which belongs to the polyester series, is composed of 1.4-pbt butanediol (1.4-Butylene glycol) and terephthalic acid (PTA) or terephthalate (DMT) poly condensation, and the mixing procedure made the milky white translucent to opaque, crystalline thermoplastic polyester resin through. Collectively referred to as thermoplastic polyesters, or saturated polyesters, together with PET. 10% glass fiber reinforced, 20% glass fiber reinforced, 30% glass fiber reinforced, flame retardant, mineral filler, glass mixing, high temperature resistance, fire resistance, hydrolysis resistance, glass fiber, heat stabilizer, lubricant ultraviolet resistance, food grade, grade, high flow conductivity. Used in household appliances (food processing blade, vacuum cleaner element, electric fan, hair dryer shell, coffee containers etc.), electrical components (switches, motor shell, fuse box, computer keyboard, etc.) automobile industry (Radiator Grilles body panels, wheel covers, doors and windows components etc.).
