Co-extruded rubber seals

Advantages of EPDM products:
 
EPDM most maining 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 wodows and doors in construction industry and many kinds of strips used on machines.
 
At present, EPDM is the most popular material for extrusion profiles. EPDM profiles include solid rubber profiles, sponge rubber profiles, compound co-extruded profiles, Static electricity flocking sealing strips, Cottonbatting-all-steel composite sealing strips etc.
 
The followings are some drawings and pictures of Cottonbatting-all-steel composite sealing strips:
