TPX™ Polymethylpentene (PMP)

The TPX™ family of Polymethylpentene (PMP) polyolefin resins offer a unique combination of Transparency, Heat Resistance and Releasability. With low haze values, and low refractive index, TPX™ exhibits transparency equivalent to glass or acrylic. With a high melting point and extremely low water absorption rate, TPX™ is an excellent choice for items that require steam sterilization. Because the surface tension of TPX™ is very low, and the product displays excellent peeling characteristics, its Releasability properties are truly unique. Please download the TPX™ Physical Properties Table.

The very low density of TPX™ offers the potential for significant weight reduction of the final product. TPX™ can be injection molded, blow molded, or extruded into film, rods or sheets. TPX™ is manufactured only by Mitsui Chemicals, Inc. and is available in *pellet form.

TPX™ applications include:

  • Animal Cages
  • Cosmetic Caps and Tubes
  • Heat Resistant Non-Woven Materials
  • Labware
  • LED Molds
  • Mandrels and Sheaths for Rubber Hose Production
  • Medical Devices
  • Microwavable Food Containers
  • Release Film
  • Release Paper for Synthetic Leather
