Product Description

Description: Series of SR 2100 UOR are silicone rubber compounds which are vulcanization molding by adding 
curing agents. (The curing agents should be chosen according to process requirements.)

Special properties:
       Excellent physical strength of raw rubber.
      Barely structured in a long-term storage.
      Low compression set.
      Good thermal stability, up to 225ºC
      Excellent resistance to oil (low swelling).
      Being able to be mixed with other rubbers.

Main applications:
SR2100 UOR series can be used to manufacture mechanical rubber goods which require 
low compression set and good oil resistance. This series is suitable for molding, injection, 
extrusion process.
