Description
Automotive Sealing Strip Introduction

Sealing Performance
The primary function of EPDM automotive sealing strips is to create a tight and reliable seal. Whether it's around car doors, windows, trunks, or hoods, these strips effectively prevent the ingress of water, dust, dirt, and noise. Their inherent elasticity allows them to conform closely to the mating surfaces of the vehicle body, forming an airtight and watertight barrier.
Temperature Resistance
EPDM sealing strips can operate effectively within a wide temperature range, typically from - 40°C to 120°C . In extremely cold conditions, EPDM remains flexible, avoiding brittleness and cracking that could compromise the seal. In high - temperature environments, such as those near the engine or in hot climates, it resists softening and losing its shape, ensuring continuous and reliable sealing performance throughout the vehicle's operating temperature spectrum.


Durability and Longevity
Due to its excellent resistance to weathering, chemicals, and temperature variations, EPDM sealing strips have a long service life. They can withstand years of exposure to the harsh automotive environment, including frequent door openings and closings, vibrations, and mechanical stress. This durability reduces the frequency of replacement, lowering maintenance costs for vehicle owners and contributing to the overall reliability of the vehicle.

Material Properties
EPDM is a type of thermoset elastomer composed mainly of ethylene, propylene, and a small amount of diene monomer. This unique chemical structure endows it with exceptional resistance to a wide range of environmental factors. It has outstanding weather resistance, capable of withstanding long - term exposure to sunlight, rain, snow, and extreme temperatures without significant degradation. Additionally, EPDM shows excellent chemical resistance, resisting attacks from common automotive fluids such as engine oil, gasoline, coolant, and various cleaning agents.
1. Why choose EPDM for automotive sealing strips?
EPDM is ideal due to its exceptional weather resistance (UV, ozone, extreme temperatures), chemical resistance to oils and coolants, and high elasticity for tight seals that reduce noise and prevent leaks.
2. Are EPDM strips durable?
Answer: Yes. EPDM resists aging, abrasion, and degradation from automotive fluids, providing long-lasting performance (10+ years) with minimal maintenance.
3.Can EPDM strips be easily installed?
Yes. Their flexibility and pre-applied adhesives or clips simplify installation, fitting most vehicle contours without specialized tools.
