PBT - Polybutylene terephthalate

Polybutylene terephthalate (PBT) belongs to the family of polyesters. This semi-crystalline polymer has good electrical insulating properties, excellent heat resistance, good resistance to chemical agents. It is imperative to dry the material properly before processing.

Widely used in applications with thermal and electrical constraints (contactor boxes, switches), in household appliances, etc.
