In recent years, industry has demanded a range of materials that not only possess strength, wear properties, heat and chemical resistance but materials that are less resistant to the build-up of a static charge. Teacform™ SD is a natural coploymer acetal with static dissipative characteristics. Teacform™ SD (Static Dissipative) l contains no carbon fibers or powders and is generally accepted for clean room use. With its surface resistivity of 109 to 1011 ohm/square and its excellent bearing and wear characteristics, TECAFORM™ SD is ideal for moving components which may experience frictional or fluid-flow static charges.
