polymethylpentene

polymer

Polymethylpentene (PMP) is a lightweight, crystalline polyolefin thermoplastic characterized by a low density and high transparency, making it a premium alternative to polypropylene for demanding applications. It is widely used in medical devices, laboratory equipment, and consumer products where clarity, chemical resistance, and thermal stability are critical; engineers select PMP over commodity plastics when the combination of optical clarity, low density, and superior chemical resistance justifies the higher material cost.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
