Kaxite manufactures Hard Mica Sheet. For every 1/16” of EPDM, a one ply layer of fabric such as nylon, lightweight nylon or fiberglass. Cloth-inserted rubber adds enhanced stability and reduces gasket creep. It is perfect for belts and gaskets that are exposed to moisture and harsh weather conditions.
The composition of cloth inserted EPDM rubber sheet is ideal for mechanical fastening gaskets. Cloth inserted EPDM offers the same properties as conventional EPDM rubber, such as weather resistance, with the enhanced stability of cloth inserted products.
Cloth inserted EPDM rubber sheet adds durability and enhanced strength under hot or cold loads and is commonly used for gasketing applications. Additional uses for cloth inserted EPDM rubber include conveyor belts and high strength diaphragms
We also offers fiberglass inserted EPDM that is known for its durability in applications requiring gasket stability. The fiberglass reduces gasket creep in applications where heavy pipe, joint or structure loading occurPDM rubber material sheet is a great weather resistant material.
Inserted cloth Fabric: Nylon, glassfiber, cotton or other fabrics
