Ethylene Propylene Diene (EPDM)

Ethylene Propylene Diene Monomer (EPDM) rubber is a type of synthetic rubber that is widely used due to its excellent properties and versatility. It is produced by the copolymerization of ethylene, propylene, and a small amount of diene monomer, typically either dicyclopentadiene (DCPD), ethylidene norbornene (ENB), or vinyl norbornene (VNB).

Properties

• Outstanding resistance to heat, ozone, weathering, and aging
• Excellent electrical insulation
• Good resistance to polar substances, acids, alkalies, ketones, and many other chemicals
• Exhibits low electrical conductivity
• Maintains its flexibility even at low temperatures

Applications

• Gaskets and seals
• Weatherstripping
• Radiator hoses

Industries

• Automotive
• Construction 
• Electrical insulation
• HVAC systems
• Outdoor applications

Overall, EPDM rubber's combination of properties makes it a preferred choice for applications where durability, weather resistance, and flexibility are critical.
