1. What is EPDM Rubber?

Chemical Identity:
EPDM is a polymer synthesized by copolymerizing ethylene (E), propylene (P), and a small amount of diene monomer (D). Its unique “ternary” structure delivers dual advantages:

Ethylene + Propylene: Forms a backbone resistant to aging and chemical corrosion

Diene Monomer: Introduces crosslinking sites for vulcanization and elasticity

Core Performance Highlights:
         Weather Resistance King: Withstands UV rays, ozone, and extreme temperatures (-50°C to 150°C)
         Anti-Aging Expert: Service life of 20-30 years
         Sealing Guardian: Low gas permeability, high resilience
         Eco Champion: Non-toxic, odorless, and recyclable

2. Where You Encounter EPDM Daily
