SSP1773 is a 50-durometer silicone rubber that meets the phyiscal requirements in the AMS 3302 specification. This heat-cured elastomer uses various peroxide catalyst systems. SSP supplies this aerospace silicone as a ready-to-mold compound or as compression molded sheet stock. It’s available in red, gray, and brown.
The AMS 3302 specification covers silicone rubber in the form of sheets, strips, tubing, extrusions, and molded shapes. SAE International, a professional association and standards-developing organization, defines Aerospace Material Specifications (AMS) like AMS 3302.
The shelf life for uncatalyzed SSP1773 is indefinite, but this military and aerospace silicone may need freshening after 1 to 2 years. When catalyzed, the shelf life is 2 to 6 months. Cold storage will extend the shelf life for this general-purpose silicone rubber.
The AMS 3302 spec is available from SAE International. The table below shows test data for SSP1773.
