Product Details

Seal Material Series > Non-asbestos rubber sheet

    Non-asbestos rubber sheet

    Materials:

     

    Made of organic fibers(e.g aramid fiber), inorganic fibers, NBR rubber and a small amount of fillers processed by calendering and vulcanizing processes.

     

    Applications:

     

    For sealing water, steam, inert gas, weak acid and alkali and general chemical.

    Sealing fuel, oil-based lubricant, such as motorcycle engine, general machinery engine and automobile engine and petrochemical products.

     

    Advantages

     

    Compared with the other kinds of gaskets, this one is soft and flexible with advantages of better joint to flange and no corrosion.
