EPM - Ethylene Propylene Monomer {EPR}

EPR (Ethylene Propylene Rubber) is a type of synthetic rubber that offers a range of properties suitable for various applications. Here are some key properties of EPR rubber compound:

  1. Weather Resistance: EPR rubber is known for its excellent resistance to weathering, ozone, and UV radiation. It can withstand exposure to sunlight, heat, and outdoor elements for extended periods without significant degradation.

  2. Heat Resistance: EPR rubber exhibits good heat resistance, allowing it to withstand elevated temperatures without losing its physical properties. It can typically withstand temperatures ranging from -40°C to 150°C (-104°F to 302°F) depending on the specific formulation.

  3. Electrical Insulation: EPR rubber is widely used as an electrical insulator due to its excellent dielectric properties. It offers good resistance to electrical current flow and can effectively isolate conductive components.

  4. Chemical Resistance: EPR rubber has good resistance to a wide range of chemicals, including acids, alkalis, polar solvents, and many organic compounds. However, it may not be suitable for certain hydrocarbons and oils.

  5. Flexibility: EPR rubber exhibits high flexibility and elasticity, allowing it to deform under pressure and return to its original shape. It can withstand repeated bending and stretching without significant deterioration.

  6. Low Temperature Flexibility: EPR rubber retains its flexibility even at low temperatures, making it suitable for applications in cold climates or where exposure to sub-zero temperatures is expected.

  7. Tensile Strength: EPR rubber has good tensile strength, meaning it can withstand pulling forces without breaking or tearing apart. The specific tensile strength can vary depending on the formulation and curing process.

  8. Compression Set Resistance: EPR rubber offers excellent resistance to compression set, which is the ability to recover its shape after being compressed or deformed. This property is particularly important in gasket and sealing applications.

  9. Water Resistance: EPR rubber has good resistance to water absorption, making it suitable for applications where exposure to water or moisture is expected.

  10. Aging Resistance: EPR rubber compounds generally exhibit good resistance to aging and degradation over time, ensuring their long-term performance and durability.

It’s important to note that the specific properties of EPR rubber can vary depending on the formulation, compounding ingredients, curing process, and other factors. we make compounds to meet specific application requirements EPR rubber compound.
