TECAFORM® SD
聚甲醛（POM）共聚物
Ensinger Inc.
產(chǎn)品說明:
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 resistive to the build-up of a static charge. Ensinger has a family of such materials; their properties are listed on the reverse side of this sheet and described below.
Ensinger's static dissipative acetal 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.
