Material Notes:

This grade is highly recommended for film extrusion; also for injection molding, fiber extrusion and blow molding.TPX® is semi-crystalline, transparent, very light and - for a polyolefin - expensive. It has good release characteristics and good high frequency electrical and valuable acoustic/ultrasonic properties. Applications include medical and laboratory apparatus, microwave components and cookware and electronic components.Information provided by Goodfellow. TPX® is a trademark of Mitsui.
