Specification Grade Silicones

DMS Silicone

DMS silicones meet Douglas Material Specifications,  a set of standards developed by the former Douglas Aircraft Company and now managed by The Boeing Company. DMS specifications define material properties such as durometer (hardness), tensile strength, and temperature resistance to ensure quality, consistency, and safety in aircraft manufacturing, including gaskets, seals, and other aircraft components. DMS silicones and fluorosilicones are used in aerospace, and military applications.

Key Aspects of DMS Silicones

Military and aerospace DMS silicone materials were developed to support efficient, standardized, and cost‑effective production across the industry, with many specifications now maintained under Boeing’s quality system. These materials are supplied as solid silicone sheets, sponges, or uncured compounds suitable for molding or extrusion, and they are engineered for thermal stability across the wide temperature ranges encountered in high‑altitude flight.

DMS silicones provide strong environmental resistance to ozone, UV exposure, and weathering, while offering low compression set and meeting stringent aerospace flammability and safety requirements. Because of these performance characteristics, DMS silicone materials are widely used in aircraft seals, gaskets, electrical insulation, and other high‑reliability components.
