Crastin® PBT Thermoplastic Polyester Resin

Crastin® Polybutylene Terephthalate For Industrial Applications

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

Crastin® PBT offers stiffness, toughness as well as excellent electrical insulation properties and beautiful surface finishes.

Crastin® PBT provides excellent dimensional properties and stability versus moisture (from a molding and performance standpoint) and good heat resistance. These properties make it particularly well-suited for lighting bezels, connectors, electrical components, distribution boxes and fiber optic cable jackets. Crastin® PBT is also available in FDA and EU approved grades for food and cosmetics applications.

When designing with products that require electrical insulation systems (EIS), DuPont™ Crastin® PBT meets the most stringent electrical insulation standards. DuPont offers the industry’s largest portfolio of EIS pre-approved by Underwriters Laboratories (UL) grades and recognized to IEC standards. 

DuPont™ Crastin® PBT  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. Latest product families include:
