Choosing the Right Seal: A Guide to Weatherstrip EPDM Materials
2025-10-29
 
1. EPDM Rubber: The Industry Standard
Ethylene Propylene Diene Monomer (EPDM) is the most widely used material for weatherstripping, and for good reason.
Excellent Weather Resistance: EPDM boasts outstanding resistance to ozone, UV radiation, and extreme temperatures (typically from -40°C to +125°C). This makes it incredibly durable against sun cracking and weathering.
Good Flexibility and Compression Set: It maintains its elasticity over time, ensuring a consistent seal after repeated compression cycles.
Cost-Effective: It offers a superior balance of performance and cost, making it the go-to choice for high-volume applications like automotive door seals and residential window seals.
Ideal for: Automotive sealing systems (doors, windows, trunks), architectural window and door seals, and industrial applications. It is the default choice for most standard scenarios.
