Product Description

Description: SR 1200 UTH series is a silicone rubber compound, which is vulcanized and molded after adding vulcanizing agent (the vulcanizing agent is selected according to the needs of the process).

 

Special properties:

           Excellent raw rubber strength
          It is not easy to be structured in long-term storage.
          No need of secondary vulcanization
          Good thermal stability, heat resistance up to 315ºC
          Can be used for mixing with other silicone rubber

Main applications:

           Suitable for occasions with high temperature resistance requirements, such as UL heat-resistant cable, bronzing rubber roller,seal&gasket, etc.

 

Characteristics:

               Type (according to GB/T 5576-1997)................................VMQ
               Natural color...................................................................... Color Beige


Curing Condition:

        After addition of 1.1% of 2,5-dimethyl-2-5-di(tert-butylperoxy) (at 45%) and

        vulcanization for 5min at 175°C.
