DETAILS

AMS 3302 Silicone Rubber, 50 Durometer

SSP-1773 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.

AMS 3302 Specification

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.

AMS 3302 Shelf Life

The shelf life for uncatalyzed SSP-1773 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.
