Ethylene-Propylene-Diene Terpolymer (EPDM) is a versatile synthetic rubber known for its exceptional durability and resistance to various environmental factors. It's a terpolymer, meaning it's composed of three different monomers: ethylene, propylene, and a diene. The diene component, typically dicyclopentadiene (DCPD) or ethylidene norbornene (ENB), provides cross-linking sites, enhancing the rubber's elasticity and strength.   

Key Properties:

Excellent Weather Resistance: EPDM exhibits outstanding resistance to UV radiation, ozone, and weathering, making it ideal for outdoor applications.   

Chemical Resistance: It is resistant to a wide range of chemicals, including acids, alkalis, and many organic solvents.   

Heat Resistance: EPDM can withstand high temperatures without significant degradation, making it suitable for demanding environments.   

Flexibility: It maintains flexibility at low temperatures, ensuring reliable performance in cold conditions.   

Electrical Insulation: EPDM possesses excellent electrical insulating properties, making it suitable for various electrical applications.
