Military Specification silicone

ZZ-R-765 post-cured SILICONE sheet

Our post-cured military specification silicone sheet is designed to be used in applications where higher physical properties and lower compression set are needed. Military and Aerospace applications often require silicone with high temperature resistance, crack resistance and flex resistance for various seals and vibration-isolating uses. This ZZ-R-765 specification grade silicone sheeting is available in 40-80 durometer.

ZZ-R-765E (A-A-59588) CL 2A/2B

  • Is compliant with Federal specification ZZ-R-765E 2A for high temperature resistance in 40, 50, 60, 70, 80 shore A durometer hardness values.
  • Also compliant with Federal specification ZZ-R-765E 2B for high temperature resistance and low compression set in 40, 50, 60, 70, 80 shore A durometer hardness values.
  • ZZ-R-765E (A-A-59588) is a specification that covers three classes of silicone rubber in various grades. Class 2 is a reference to where resistance to extreme high temperature is required to approximately 219°C (425°F) and low temperature resistance to about -62°C (-80°F). Class 2B material also possesses low compression set.
