Western Rubber & Supply, Inc.’s A-A 59588A and AMS-3326 silicones are heat cured, mil-spec rubber molding compounds. A-A series materials are designed to meet the A-A 59588A Class I A&B Group 40-70 and A-A 59588A Class 2 A&B Group 25-80 specifications (formerly ZZR-765). AMS-3326 silicone is designed to meet the fuel resistant requirements outlined in the Aerospace Material Specification (AMS). Class 1 silicones provide extreme low temperature resistance, while Class 2 silicones are a general purpose compound with high temperature resistance. Silicone in general is known for its excellent weather, oxidation and ozone resistance. Our materials are available from 25 to 80 durometer and can be custom molded into required shapes.
