CRESTER Polybutylene terephthalate (PBT)

CRESTER is a brand name for Polybutylene terephthalate (PBT) compounds. PBT is a semi-crystalline engineering thermoplastic and a type of polyester.

Chemical structure and polymerization

PBT is produced by polycondensation of terephthalic acid with 1,4-butanediol using special catalysts.

Key features

CRESTER is characterized by high stiffness and strength, very good dimensional stability, low water absorption and good chemical resistance.
CRESTER can provide reliability, durability and a cost advantage in electrical and electronic applications, automotive lighting bezels
