How is Ultradur® manufactured?
The main methods, however, are injection molding and extrusion. Complex moldings are economically manufactured in large numbers from Ultradur ® by injection molding. The extrusion process is used to produce film, semi-finished products, pipes, profiled parts, sheet and monofilaments.
Why choose Ultradur ® PBT?
Ultradur ® for applications in the construction and electrical appliances sectors and increasingly in automotive engineering, which place special requirements on PBT’s flammability. The standard fire-retardant grades are unreinforced and available with 10 to 30 percent glass-fiber reinforcement.
What are Ultradur ® grades?
The Ultradur ® grades are polyalkylene terephthalate molding compounds based on polybutylene terephthalate. Ultradur ® is produced by polycondensation of terephthalic acid or dimethyl terephthalate with 1,4-butanediol using special catalysts.
