TPX Polymethylpentene (PMP) is a unique semi-crystalline thermoplastic known to have the lowest density of any commercial grade polymer available at 0.82 g/cc. Its typical color is a semi-opaque milky white, however in thinner gauges of sheet and film the material is transparent.
The TPX offer a unique combination of heat resistance and release characteristics. Because the surface tension of TPX is very low, the product displays excellent release and peeling characteristics. In addition, the extremely low density of TPX offers the potential for significant weight reduction of the final product.
Applications include release films, lightweight structural parts, and hollow fibers. PMP is FDA compliant and used in many food and beverage applications
