Ethylene Propylene Diene Monomer Rubber (EPDM) has a wide range of applications, especially in automotive parts and various products that require weather resistance. It meets the performance requirements for many types of industrial and construction materials.
Main Features:
- Outstanding aging resistance, ranking among the best in general-purpose rubbers.
- Superior insulation and dielectric properties compared to base rubber, with excellent water resistance after immersion.
- Excellent resistance to a variety of strong polar chemicals and acids (excluding concentrated sulfuric acid).
- Excellent elasticity and resistance to permanent deformation, maintaining flexibility at low temperatures down to -57 °C.
- Can be filled with large amounts of fillers without significantly compromising product performance.
- Not resistant to oil.
- Poor self-adhesion and adhesion to other materials, making processing more difficult.
- Good resistance to ozone, allowing it to withstand high concentrations without degradation.
- Resistant to polar liquids such as ketones, alcohols, and aqueous solutions.
Main Applications:
- Suitable for automotive bumpers, bridge shock absorbers, various construction waterproof materials, pavement pads, rubber sheets, and protective sleeves.
- Ideal material for manufacturing electric cables and cable sheaths, particularly suitable for producing low-, medium-, and high-voltage cable insulation layers.
- Used for making various automotive parts, glass sealing strips, and heat-resistant rubber products.
- Suitable for manufacturing components that require resistance to heat, ozone, weathering, and corrosion.
- Can be used in tire manufacturing, inner tubes, and water bladders, though air permeability issues must be addressed.
