PMP(TPX)

Polymethylpentene

Product Description:

PMP is a lightweight, high temperature polyolefin with exceptional acoustical and electrical properties. PMP has low moisture absorption and excellent chemical resistance. TPX is also used for electrical insulating applications requiring high dielectric strength and low dielectric constant. PMP has the lowest specific gravity of any commercially available thermoplastic (0.835), making it an excellent choice for lightweight structural parts. Additionally, natural PMP is FDA compliant for use in food processing machinery.
