Description

Poly(Methylpentene) (CAS NO 9016-80-2) is a high-performance thermoplastic polymer known for its exceptional optical clarity, high melting point, and excellent chemical resistance. This material is valued for its unique combination of transparency, thermal stability, and low density, making it a superior alternative to other clear plastics in demanding environments. It is essential for manufacturers in the medical, laboratory, packaging, and specialty optics industries who require durable, transparent components that can withstand sterilization and harsh chemicals.

Application

• Medical & Laboratory Ware: Used for manufacturing transparent syringes, cuvettes, petri dishes, and centrifuge tubes due to its clarity, autoclavability, and chemical inertness.
• High-Temperature Packaging: Ideal for microwaveable containers, oven-proof trays, and lids where clarity and heat resistance up to ~200°C are critical.
• Optical Components: Serves as a lightweight material for lenses, light guides, prisms, and display covers where high transparency and low birefringence are required.
• Electrical Insulation: Employed in coil bobbins, connectors, and insulating films due to its excellent dielectric properties and thermal stability.
• Chemical Process Equipment: Used for sight glasses, level gauges, and transparent piping in chemical plants to monitor processes involving corrosive substances.
• Specialty Films & Release Layers: Produces high-temperature release films and membranes for industrial lamination processes.

Quality Control

Our Poly(Methylpentene) is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Quality is verified through a series of tests including melt flow index (MFI), thermal analysis (DSC for melting point), spectroscopic identification (IR), and clarity/color measurement. Certificates of Analysis (COA) detailing purity, physical properties, and performance specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and direct heat sources to maintain polymer integrity.
