CRASTIN by CELANESE
Celanese™ Crastin® PBT (polybutylene terephthalate) thermoplastic polyester offers exceptional resistance to heat, creep and solvents, processing ease and good economics for a variety of applications. Among its most notable characteristics:
Dimensional stability to go where nylon can’t with part performance virtually unaffected by changes in ambient humidity.
This characteristic is especially valuable in auto lighting bezels, connectors and water valves
Excellent dielectric and electrical insulation properties, with high arc resistant grades, make Crastin® especially suited for connectors, relays, switches
