Data Sheet

TPX Polymethylpentene (PMP) is a crystalline thermoplastic offering a unique combination of a very low-density value (0.82 g/cc), permeability, heat resistance and releasability (very low surface tension). TPX has outstanding low-dielectric properties which makes it an excellent candidate for high-frequency applications. TPX is an excellent choice for items that require steam sterilization. Advantages of TPX:

  • Low moisture absorption
  • Dielectric properties
  • Chemical resistance
  • Heat resistance
  • Excellent acoustical properties


  • Speaker cones
  • Gas separating membranes
  • Release films
  • Carrier films for ceramic slurry
  • Antennas
  • Ultrasonic imaging equipment
