With more than 100 formulations available, Crastin® Polybutylene Terepthalate is the resin of choice for cost-effective performance across a wide spectrum of automotive, industrial, and consumer applications.
Designers and engineers for everything from automotive electrification to cosmetics packaging rely on Crastin® for stiffness and toughness, superior electrical insulation, and exceptional surface finishes. It’s also preferred over other materials for its excellent dimensional properties, stability versus moisture and its heat resistance.
Crastin® is extremely versatile. It’s available in FDA and EU approved grades for food and cosmetics applications.
Crastin® grades are also offered that meet the most stringent electrical insulation standards (EIS) and enables Celanese to offer the industry’s largest portfolio of materials pre-approved by Underwriters Laboratories (UL) and recognized to International Electrotechnical Commission (IEC) standards.
Plus, Crastin® offers manufacturers the advantage of superior flow qualities. It’s easy to process on conventional injection molding equipment. And, we offer a wide range of grades designed specifically for low warpage, hydrolysis resistance, blow molding, and extrusion.
Made globally in three regions, Crastin® is available wherever you are.
Innovate better mechanical gears, furniture, sporting goods, appliances, and more with the strength and stiffness of Crastin®.
Crastin® is ideal for electrical and electronic plastics, encapsulation materials, and photovoltaic panels and parts.
With its stability in the presence of moisture, Crastin® is ideal for automotive, appliance, and medical device applications.
High heat resistance makes Crastin® the resin of choice for applications that require durability in high temperatures.
Reduce cycle times for increased cost efficiency, reduce molding machine size due to lower filling pressure, and lower energy consumption during molding with Crastin®.
