    • Electrically conductive sheeting (resistivity well below 106 ohms) and methods for producing such sheeting are disclosed. Preferred sheeting is a fabric having outer plies of flexible polymeric film, such as, polyvinylchloride, and a core layer of rubber, such as, synthetic acrylonitrilebutadiene rubber which may be blended with polyvinylchloride resins, the rubber containing at least from about 25 to about 40 percent by weight of electrical grade carbon black. The outer polymeric layers are perforated in a density of from about 5 to about 25 perforations per square inch or greater, the perforations preferably having a size on the order of from 0.003 to 0.012 inch (3 to 12 mils). The perforations may be formed prior to or after coating or bonding of the polymeric films with the rubber core layer, and the final product may be pressed to seal the perforations providing a nonporous conductive sheeting material. In one preferred embodiment one exterior surface of the sheeting is provided with a coating or layer which dissipates or reflects radiant energy.
    • 公开了导电片(电阻率远低于106欧姆)和制造这种片材的方法。 优选的片材是具有柔性聚合物膜的外层的织物,例如聚氯乙烯和可以与聚氯乙烯树脂共混的合成丙烯腈 - 丁二烯橡胶的核心层,橡胶含有至少约25至约40 重量百分比的电级炭黑。 外部聚合物层以每平方英寸或更大的约5至约25个穿孔的密度穿孔,穿孔优选具有0.003至0.012英寸(3至12密耳)的量级。 穿孔可以在聚合物膜与橡胶芯层的涂覆或粘合之前或之后形成,并且最终产品可以被压制以密封提供非多孔导电片材料的穿孔。 在一个优选实施例中,片材的一个外表面设置有耗散或反射辐射能的涂层或层。

    • This invention concerns non-porous, polymeric articles having active properties, and methods for producing such articles. Plastic, rubber, or other natural and synthetic polymeric articles are provided with active chemical and/or physical properties, such as, antibacterial, antifungal, pesticidal, insecticidal, animal repellent, odorous, antistatic, electrically conductive or other properties or combinations of properties, by applying to a surface of the article selected activating agents which migrate or move throughout the body of the article to impart an effective level of activity throughout the article and/or on a surface other than the one to which the activating agents have been applied.
