Designers, engineers, and manufacturers rely on Crastin® PBT for stiffness and toughness, superior electrical insulation
properties, and exceptional surface finishes. Crastin® is also preferred for its excellent dimensional properties and stability versus moisture as well as its heat resistance.
Crastin® is extremely versatile. It’s available in Food contact application and EU approved grades for food and cosmetics applications, and it meets the most-stringent electrical insulation standards. It enables DuPont to offer the industry’s largest portfolio of EIS pre-approved by Underwriters Laboratories (UL) grades and recognized to IEC standards.
DuPont™ Crastin® PBT offers manufacturers the advantage of superior flow qualities. It’s easy to process on conventional injection molding machines. It is available in a wide range of grades designed for low-warpage, hydrolysis resistance, and for blow-molding and extrusion.
With Crastin®, DuPont materials science experts help customers gain cost efficiency without compromising on performance.
