Filled PMP is a subcategory of Polymethylpentene. The additative is added during the manufacturing process. Its molding pressure ranges from 1 to 10 MPa.

Polymethylpentene, also known as PMP, is a thermoplastic polymer. It has a very low density and is transparent. It has excellent chemical resistance, low moisture absorption, and exceptional acoustical and electrical properties. PMP can be found in sonar covers, speaker cones, ultrasonic transducer heads, and lightweight structural parts. It is also FDA compliant for use in food processing machinery. Polymethylpentene is often used in films and coatings for gas permeable packaging.
