Rubber Seal ? EPDM main feature is its excellent resistance to oxidation, ozone resistance and erosion resistance ability. And also insulation property is good. Based on the good property, EPDM is widely used in extrusion industry such as auto door seals and weather strip, sealing strips for windows and doors in construction industry and many kinds of strips used on machines.

At present, EPDM is the most popular material for extrusion profiles. EPDMprofiles include Solid Extrusions, Foam Extrusions, Solid & Sponge Extrusions, Solid & Flocking Extrusions, Rubber/Plastic & Steel Strip/Wire Composite Extrusions, Solid & Sponge & Steel Strip/Wire Composite Extrusions etc.
1.The use of rubber seal: Rubber seal is widely used in various kinds of industry, including auto parts, doors, ? window, machine and construction industry. Rubber seal could work during -40 centigrade to 260 centigrade.

2.The function of rubber seal: Rubber seal could stop air, water and dust enter the machine system, which ? could protect the machine or parts to be healthy and working well.

3.The advantage of rubber seal: The flexibility and anti-aging capability of EPDM rubber seal is very good. ? 4.The kinds of rubber seal: There are solid rubber seal, sponge rubber seal, hollow rubber seal and ? composite rubber seal.

5.Technology Process: Extruded. ? The next is our test report from our quality control department. ?
