Oil-resistant rubber sheet series
Produced by blending, rolling and vulcanizing fiber, rubber and filling materials. According to different complex fibers, there are oil-resistant asbestos rubber sheet and oil-resistant asbestos-free rubber sheet. The main ingredient in asbestos series is asbestos-mine fiber. The thermostability is 500℃, and the mechanical strength is better than organic fiber. The main ingredient in asbestos-free series is aramid fiber. The thermostability is around 200℃. Mechanical strength is weaker than asbestos, but compactness is better than asbestos. And it is a kind of environment-friendly sealing material. |
