Description

1-Pentene, 4-Methyl-, Polymer With Ethene CAS NO 25213-96-1 is a synthetic copolymer derived from 4-methyl-1-pentene and ethene (ethylene), forming a versatile polyolefin material. This copolymer is valued for its unique balance of properties, including excellent optical clarity, chemical resistance, and a high melting point relative to other polyolefins. It is primarily utilized in the production of high-performance films, specialty packaging, and molded components for the medical, optical, and electronics industries.

Application

• Medical Device Packaging: Used to manufacture rigid, sterilizable containers and blister packs due to its clarity and chemical resistance.
• Optical Films and Lenses: Serves as a base material for light-guide plates, lenses, and display films where high transparency and thermal stability are critical.
• Specialty Food Packaging: Employed in high-clarity films and containers for modified atmosphere packaging (MAP) and microwaveable trays.
• Laboratory and Diagnostic Ware: Used for producing transparent, chemically resistant test tubes, cuvettes, and sample containers.
• Electrical Insulation: Acts as an insulating material for wires and cables, leveraging its good dielectric properties.
• Polymer Modification: Functions as a compatibilizer or impact modifier in blends with other polyolefins to enhance specific performance characteristics.
