The difference between EPDM weatherstrip and silicone strips

51317008911

There are some differences between EPDM sealing strips and silicone strips in terms of material properties, application areas and characteristics:

1. Material properties:
EPDM sealing strip: EPDM is a synthetic rubber with good weather resistance, oxidation resistance, acid and alkali resistance and aging resistance. It has good resistance to most common chemicals and water vapor.
Silicone strip: Silicone is a polymer material based on a silicon-oxygen bond structure. It has excellent high temperature resistance, weather resistance, electrical insulation and stable physical properties. It also has good resistance to many chemicals and solvents.

2. Application fields:
EPDM sealing strips: EPDM sealing strips are commonly used in construction engineering, automobile manufacturing, power equipment, water supply and drainage systems and other fields. It is suitable for outdoor environments and can effectively prevent the penetration of water, air and dust.
Silicone strips: High-temperature resistant silicone strips are commonly used in high-temperature environments, food processing, medical equipment, electronics industries and other fields. It has excellent high temperature resistance, maintaining its elasticity and physical properties from -60°C to +200°C.

3. Features:
EPDM sealing strip: EPDM sealing strip has good weather resistance, aging resistance and acid and alkali resistance. It has high mechanical strength and good tear resistance and pressure resistance.
Silicone strips: Silicone sealing strips have excellent high temperature resistance, oxidation resistance and electrical insulation. It is very soft and elastic and suitable for sealing surfaces of complex shapes and sizes.

It should be noted that the above are only general differences. The actual selection should determine the most suitable sealing strip material based on specific requirements and application environment.
