| Crown Plastics DuraSurf™ ASC is an Anti-Static/Conductive UHMW that possesses the highest level of conductivity in the industry with a surface resistivity of 10² – 10³. DuraSurf™ ASC protects against static build up that can occur in powder conveying and dust collection as well as provide protection in electronics applications such as appliance, mail sorting, copiers, printers and computers. Eliminating static reduces safety concerns in a wide array of industries. Dust collection hoppers are virtual combustion chambers. A static shock could ignite airborne particles creating an explosion. These volatile areas can be made much safer by lining them with DuraSurf™ ASC, available in wear strips or with adhesive backing.
