Celanex® thermoplastic polyester (PBT) is a semicrystalline structure based on polybutylene terephthalate that provides high strength, rigidity and toughness, low creep even at high temperatures and resistance to a wide range of chemicals, solvents, oils and greases.
Celanex® PBT is especially suited as a sliding partner for Hostaform®/ Celcon® POM. It features excellent dimensional stability, low moisture absorption and powerful insulation resistance.
Depending on market requirements, the Celanex PBT flame-retardant system is low in migration and halogen-free.
Various grades of Celanex PBT hold regulatory approvals including VDE or UL approvals for the electrical and electronic market, and FDA approval for the nutrition and medical markets.
