DuPont™ Crastin® PBT: Electrical Plastic for Connectors, Relays and Switches
Crastin® PBT thermoplastic polyester resins, which are based on polybutylene terephthalate, feature excellent dielectric and electrical insulation properties and are available in high arc-resistant grades, making them the ideal electrical plastic for connectors, relays and switches.
With outstanding mechanical and physical properties, Crastin® delivers greater reliability, increased durability and a cost advantage over many competitive materials used in electrical and electronic applications.
For circuit breakers, relays, and connectors, Crastin® PBT resins deliver low embrittlement at high temperatures, dimensional stability, easy processing, and low out-gassing.
For encapsulation of pumps, valves, and solenoids, Crastin® PBT resins offer a unique combination of high flow, high temperature resistance, excellent barrier to moisture, and resistance to thermal shocks.
