About Stockwell Elastomerics
Stockwell Elastomerics manufactures custom gaskets, seals, cushioning pads and related elastomer components for equipment designers. Silicone rubber is its core material, complemented by silicone foams and sponges, fluorosilicones, conductive compounds and other engineered elastomers. The company describes one U.S. manufacturing site in Philadelphia, with production and customer service together. Cutting processes include die cutting, non-abrasive waterjet cutting and digital knife cutting. Molded components can use liquid silicone injection molding or rubber compression molding, while adhesive lamination and bonded assemblies address installation and layered constructions. Applications engineers assist with material selection and prototyping.
