EPDM Rubber (Ethylene Propylene Diene Monomer)

Description

EPDM Rubber is a synthetic rubber polymer made by polymerizing ethylene, propylene, and a small amount of diene. This unique composition provides EPDM with outstanding resistance to aging, ozone, UV exposure, and extreme temperatures. It is commonly used in applications that require excellent durability and resilience, especially in outdoor, automotive, and industrial sectors.

Mechanism & Features

Excellent Weather Resistance: EPDM Rubber resists UV degradation, ozone, and extreme weather conditions, making it ideal for outdoor applications.
High Temperature Stability: It retains its physical properties across a wide temperature range, from -40°C to 120°C, making it suitable for both cold and hot environments.
Chemical Resistance: EPDM offers resistance to a wide variety of chemicals, including acids, bases, and alcohols, making it perfect for industrial applications that come into contact with harsh substances.
Durability: With its superior resistance to aging and oxidation, EPDM provides long-lasting performance without cracking or hardening.
