PMP

polymer

PMP (polymethylpentene) is a semicrystalline thermoplastic polymer known for its exceptional clarity, low density, and outstanding chemical resistance across a broad range of solvents and aggressive media. It is widely used in laboratory equipment, chemical containers, and medical devices where transparency combined with durability in harsh chemical environments is critical; PMP is preferred over polystyrene and acrylic in applications requiring prolonged exposure to oils, alcohols, and organic compounds without embrittlement or stress cracking.

Regulatory Screening

Environmental

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.
