Non - asbestos rubber sheet

Non - asbestos rubber sheet

FNY non-asbestos oil resistant rubber board:

Material: with special fiber, oil resistant synthetic rubber as the main raw material, press vulcanization.

Application: used as gasket material for flange joint of oil refining equipment and distillation pipeline, automobile diesel engine and oil pipeline joint.

FXB non-asbestos rubber sheet:

Material: special heat resistant fiber, rubber as raw material, pressed.

Application: gasket material for sealing flange connection of pipes with medium such as water, steam, air, gas and lye.

Non-asbestos rubber board (no asbestos rubber board) is the aramid and other organic fibers and plant fibers and nitrile rubber, inorganic minerals at high temperature from the compression of the sealing material, because there is little asbestos fiber, suitable for the asbestos gasket no asbestos rubber board replacement products. Non-asbestos rubber board (no asbestos rubber board) not only has high strength, but also has good resilience, and has the anti-permeability performance, is a good environmental protection material in high temperature and pressure to replace asbestos gasket.
