EPDM side bulb rubber trim seal manufacturer in China
Rubber trim seals are flexible sealing materials typically used in automotive, construction, and industrial applications to create tight seals and prevent water, air, dust, or noise from entering or escaping. These seals can be used around doors, windows, hatches, and other moving parts.
Materials choose:
EPDM / Neoprene / Nitrile (Buna-N) /Silicone or PVC. PVC material with Less flexible than EPDM and offers good durability and resistance to chemicals and weathering. EPDM rubber with the excellent flexibility, UV and weather resistance.
Regarding co-extruded side bulb rubber trim seal main material is black dense EPDM and sponge EPDM with metal carrier (steel or wire carrier) insert, metal clips and gripping tougue can provide a better gripping, enhance the gripping force, which mainly used on automobile, industry, window, door, construction etc.
Our bulb trim seal can be extruded into various shapes and sizes. Currently there are over thousands kinds of mould for you choose, of course also can be do according to your drawing.
Rubber trim seal properties:
Temperature Resistance: Many rubber trim seals are resistant to high and low temperatures, ranging from -40°C to 150°C (depending on different material). Water Resistance, durability, and noise Insulation.
Air Tightness: Rubber trim seals should offer excellent resistance to water, preventing leaks in automotive, construction, or marine applications.
Durability: The seal must withstand wear and tear over time, especially in high-friction areas or environments with constant movement (e.g., car doors, industrial machinery).
Flexibility: The material should remain flexible throughout its life to ensure the seal doesn’t lose its functionality, especially in doors or moving parts.
EPDM bulb rubber trim seal with very good compression set, high tensile strength, excellent weather, ozone, UV, water, steam, high and low temperature resistance. If your product need excellent aging resistance, EPDM rubber is the best choice.
