department of defense rubber manufacturing mil-specThe defense industry often requires specification grade material for their products. Mil-spec grade materials are tough and function well in certain industry applications. Certifying a material to Mil-spec means the product maintains certain characteristics to meet physical strength, resistance to temperature, flammability and other environmental requirements. Using rubber materials that can withstand various types of environmental extremes is crucial when manufacturing products used in military and defense applications.

According to the Department of Defense, standardization documents are developed and used for products, materials, and processes that have multiple applications to promote commonality among military and defense departments, and between the United States and its allies, to maintain standardization.  the Military Departments and the Defense Agencies and between the United States and its allies, and to limit the variety of items in the military supply system.
