The Advantages of EPDM Door and Window Automotive Sealing Strips（一）
2025-05-20
Introduction
EPDM (Ethylene Propylene Diene Monomer) sealing strips are widely used in automotive door and window applications due to their superior durability, weather resistance, and sealing performance. As a critical component in vehicle manufacturing, EPDM seals ensure noise reduction, waterproofing, and thermal insulation. This article explores the key advantages of EPDM sealing strips in automotive applications.
1. Excellent Weather Resistance
EPDM rubber exhibits outstanding resistance to extreme weather conditions, including UV radiation, ozone, and temperature fluctuations (-40°C to +120°C). Unlike other elastomers, EPDM does not crack or degrade when exposed to sunlight, rain, or snow, ensuring long-term performance in automotive environments.
2. Superior Sealing Performance
EPDM sealing strips provide an airtight and watertight seal, preventing dust, moisture, and noise from entering the vehicle cabin. Their excellent compression set resistance allows them to maintain their shape and elasticity over time, ensuring consistent sealing even after repeated use.
