/  Product description  


  •  

    EPDM is with excellent allround properties. It is of many advantages, for example, outstanding anti-ozone, excellent weather resistance, outstanding chemical resistance, resistent to polar reagent like brake fluid,strong acid and alkali,alcohol and so on.

  •  

    The disadvantage is expanding too much in the ordinary mineral oil and second ester lubricating oil.

  •  

    Temperature range:-60℃~+150℃.
