| Crown Plastics DuraSurf™ ASC是一种抗静电/导电的超高分子量材料，具有业内最高的导电性，DuraSurf™ ASC可防止粉末输送和粉尘收集中产生的静电积聚，并在电器、邮件分拣、复印机、打印机和计算机等电子应用中提供保护。消除静电降低了许多行业的安全问题。集尘漏斗是虚拟燃烧室。静电冲击会点燃空气中的微粒，产生爆炸。这些易挥发的区域可以用DuraSurf™ ASC衬里使其更安全，可以用耐磨条或粘合背衬。超高分子量（UHMW），优异的耐磨性和极高的冲击耐磨性，强度符合FDA和美国农业部指导方针，无吸湿自润滑-不需要润滑油或润滑油优异的减噪性能，化学抗腐蚀性能，保持在-30℃的性能和性能符合ASTM-D-4020-81低摩擦系数 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. AVAILABLE THICKNESS .005" (.125 mm), .010" (.25 mm), .015"(.38 mm), .020" (.5 mm), .031" (.75 mm), .040" (1 mm), .050" (1.3 mm), .062" (1.57 mm), .080" (2 mm) .093" (2.35 mm), 100" (2.5 mm), .125" (3.17 mm) AVAILABLE WIDTHS All dimensions between 1/4" (6.35 mm) and 24" (610 mm) UHMW PROPERTIES Excellent abrasion and wear resistance Very high impact strength Meets FDA and USDA guidelines No moisture absorption Self-lubricating - no need for oils or lubricants Excellent noise abatement properties Chemical resistance and corrosion resistant Maintains performance and properties at -30°C Meets ASTM-D-4020-81 Low coefficient of friction |
