AMS 3325 Silicone Rubber, 60 Durometer
SSP-2496 is a 60-durometer silicone rubber that meets the fuel resistance requirements in the AMS 3325 specification, which supercedes AMS 3326. This heat-cured elastomer uses a DBPH catalyst system and is supplied as compression molded sheet stock or ready-to-mold compound. Natural color SSP-2496 can be pigmented as required.
AMS 3325 Specification
The AMS 3325 specification covers fluorosilicone rubber in the form of sheets, strips, tubing, extrusions, and molded shapes. These materials are used typically for parts requiring resistance to jet fuels and lubricating oils, but usage is not limited to such applications. SAE International, a professional association and standards-developing organization, defines Aerospace Material Specifications (AMS) like AMS 3325.
AMS 3325 Shelf Life
The shelf life for catalyzed SSP-2496 is two months. Cold storage will extend shelf left for this military and aerospace silicone.
