TPX Polymethylpentene

TPX is a 4-methylpentene-1 based olefin polymer that provides unique property and performance characteristics, unmet by conventional thermoplastics.

Manufactured by Mitsui Chemical, TPX is a crystalline polymethylpentene based olefin copolymer. TPX copolymers offer excellent electrical insulating properties, and strong hydrolysis resistance, in addition to providing optical clarity, heat and chemical resistance, gas permeability, and strong release properties. TPX copolymer possesses the lowest density among all commercially available thermoplastic polymers, providing light weight components parts and products. This transparent olefin can be processed by injection molding, blow molding, and extrusion.
