/  Product description  


  •  

    Silicon is temperature resistance whether too high nor too low, and anti-ozone, excellent hydrophobicity, appropriate air permeability, unique safe insulation.

  •  

    The disadvantage is with the worst mechanical strength in the rubber material.

  •  

    Temperature range:-100℃~300℃.
