Description
Description: This series is silicone rubber compounds with high transparency and tear resistance which are
vulcanization molding by adding curing agents. (The curing agents should be chosen according to process
requirements.)


Special properties:
     Transparent appearance, excellent physical performance.
     Resistance to crephardening in a long-term storage.
     Low compression set.
     High tear resistance.
     Excellent process performance.
     Can be used to mix with other rubbers.


Main applications:
      Suitable for molding products which require high tear resistance with complex structure
and high mechanical property. Suitable for large size extruded products such as special
cable sheath. Suitable for large size vulcanized products such as silicone rubber plate and
air bags.
      SR32XXU & SR36XXU: crescent tear is up to 30~40, right angle tear is up to around 40.
Suitable for general high tear occasions, the price is moderate.
      SR33XXU: Can be used in special occasions that require super high tear resistance meets
around 50. The price is higher.
