Crastin® PBT thermoplastic polyester resin

Crastin® Polybutylene Terephthalate For Industrial Applications

Crastin® PBT resin is available in over 100 grades for cost-effective performance across a wide range of industrial applications.

DuPont™ Crastin® polybutylene terephthalate PBT resin offers cost-effective stiffness, toughness, heat resistance, and dimensional stability. Crastin® also has excellent electrical insulation properties and surface finishes.

Crastin® polybutylene terephthalate provides excellent dimensional properties and stability versus moisture (better than nylon from a molding and performance standpoint) and good heat resistance. These properties make it particularly well-suited for lighting bezels, connectors, relays, switches, distribution boxes and fiber optic cable jackets.

DuPont™ Crastin® polybutylene terephthalate PBT resin has superior flow qualities, is easy to process on conventional injection molding machines, and has a wide range of grades designed specifically for low warpage, hydrolysis resistance, and also for blow-molding and extrusion. DuPont materials science experts can use the properties of Crastin® to help customers gain cost efficiency without compromising on performance.
