Description 

Epdm is a terpolymer of ethylene, propylene and non-conjugated diolefin,EPDM has a low specific gravity among all rubbers. It can absorb a large number of fillers and oils with little impact on properties, so it can be made into a low-cost rubber compound.

Advantage

1. Cost-effective, rubber density is only 0.86 ~ 0.90kg/m3, rubber density is the lightest commonly used rubber; And can be filled in large quantities toreduce the cost of glue. 

2. Excellent aging resistance, weather resistance, ozone resistance, sunlight resistance, heat resistance, water resistance, water vapor resistance, uv resistance, radiation resistance and other aging properties, and other unsaturated diene rubber such as NR, SBR, BR, NBR, and CR and so on when used, EPDM can play the role of polymer antioxidant or antioxidant.

3. Excellent chemical resistance, acid, alkali, detergent, animal and plant oil, alcohol, ketone, etc.; Excellent water resistance, resistance to hot water, steam resistance; Resistance to polar oil. 

4. Excellent insulation performance, volume resistivity 1016Q•cm, breakdown voltage 30 ~ 40MV/m, dielectric constant (1kHz, 20℃)2.27. 

5. The applicable temperature range is wide, the lowest temperature of -40 ~ -60℃, can be used under 130℃ conditions for a long time.

Application

1. Automotive industry: EPDM rubber in the automotive manufacturing industry should be the largest amount, mainly used in automotive sealing strip, radiator hose, spark plug sheath, air conditioning hose, rubber pad, hose, etc.

2. Construction industry: EPDM rubber in the construction industry is mainly used for plastic playground, waterproof coil, house door and window sealing strip, glass curtain wall sealing, sanitation equipment and pipe seals.

3. Electrical and electronic industry: EPDM rubber is mainly used for its excellent electrical insulation, weather resistance and corrosion resistance, and this kind of rubber is used in many electrical parts.
