Choosing the Right Seal: A Guide to Weatherstrip Materials (EPDM, TPE, PVC, Silicone) （ 一）
2025-09-23
At Hebei Fengming Plastic Products Co.,ltd., we engineer seals with precision. This guide breaks down the most common weatherstrip materials—EPDM, TPE, PVC, and Silicone Rubber—to help you understand their strengths and ideal applications.
（一）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.
