EPDM rubber strips and Santoprene rubber strips are two commonly used sealing materials, and they have some differences in material properties, characteristics and applications. Here are a few key differences between them:
1. Material composition: EPDM rubber is a kind of synthetic rubber, which is copolymerized from ethylene, propylene and diene. Santoprene rubber is a thermoplastic elastomer composed of ethylene propylene rubber and cross-linked polypropylene.
2. Physical properties: EPDM rubber has good heat resistance, weather resistance and chemical resistance. It has high elasticity and resilience, and can withstand a wide temperature range and various environmental conditions. Santoprene rubber also has good heat and weather resistance, and has high softness and elasticity.
3. Chemical resistance: EPDM rubber can resist the erosion of various chemical substances, and has good acid and alkali resistance. Santoprene rubber also has better chemical resistance to some chemicals.
4. Sealing performance: EPDM rubber sealing strip has good elasticity and resilience, which can provide a good sealing effect and prevent the penetration of air, moisture and noise. Santoprene rubber sealing strip also has good sealing performance, which can fit the sealing surface and provide an effective sealing effect.
5. Application fields: EPDM rubber sealing strips are widely used in doors and windows, automobiles, construction and industrial equipment and other fields. Santoprene rubber weatherstrips are commonly used in automotive, electronics, home appliances and industrial equipment, and are especially suitable for applications requiring UV and chemical resistance.
To sum up, the choice of EPDM rubber sealing strip or Santoprene rubber sealing strip can be considered according to specific application requirements and environmental conditions. EPDM rubber seals are suitable for applications requiring higher heat and weather resistance, while Santoprene rubber seals are suitable for applications requiring UV and chemical resistance.
