Goodfellow TPX® MX002O Polymethylpentene
Categories:	Polymer; Thermoplastic; Polymethylpentene (PMP); Polymethylpentene, Molded
Material Notes:	This grade is highly recommended for injection molding, film and mandrel extrusion; also for 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.
