Description
Material Notes:
This grade is highly recommended for paper coating or for fiber extrusion.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.
