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.
