Butyl rubber is a copolymer of isobutylene and isoprene. It is known for its low gas permeability and good electrical insulation properties. Butyl rubber is often used in applications such as inner tubes, sealing gaskets, and electrical insulation.
EPDM rubber is a terpolymer of ethylene, propylene, and a diene monomer. It is known for its excellent resistance to weathering, ozone, and heat. EPDM rubber is often used in applications such as roofing membranes, automotive parts, and conveyor belts.
In summary, butyl rubber and EPDM rubber are different synthetic rubbers with different properties and applications. Butyl rubber is known for its low gas permeability and electrical insulation properties, while EPDM rubber is known for its excellent resistance to weathering, ozone, and heat.
