Safety Information about polyvinyl chloride
许多聚氯乙烯（PVC）产品经认证符合监管机构或其他标准规定的特殊要求。用于输送饮用水的聚氯乙烯（PVC）管道必须经过NSF国际认证，以符合美国环境保护局（EPA）的安全规定。医疗和食品接触产品必须符合美国食品和药物管理局的规定。
Many polyvinyl chloride(PVC) products are certified to meet special requirements set by regulatory authorities or other standards. Polyvinyl Chloride (PVC) pipe for delivering drinking water must be certified by NSF International to conform to U.S. Environmental Protection Agency (EPA) safety regulations. Medical and food-contact products must meet U.S. Food and Drug Administration regulations.
虽然一些新的聚氯乙烯（PVC）产品有异味，但少量挥发性有机化合物（VOCs）会通过正常通风迅速消散——事实上，测试表明，乙烯基墙面覆盖物的初始气味消散速度比大多数油漆的气味快得多。聚氯乙烯（PVC）产品能够满足FloorScore®、Green Label Plus和GREENGUARD等标准中的低VOC要求。
While some new polyvinyl chloride(PVC) products have an odor, the small amount of volatile organic compounds (VOCs) emitted will dissipate quickly through normal ventilation – in fact, tests have shown that the initial odor of vinyl wall coverings dissipates much faster than odors from most paints.
聚氯乙烯（PVC）是通过聚合（连接在一起）一种叫做聚氯乙烯的化学品而制造的。法规严格限制了工作场所和制造厂排放物中的聚氯乙烯含量。制造商将尽可能多的聚氯乙烯转化为PVC，以最大限度地利用这种原料，然后使用蒸汽去除剩余的聚氯乙烯，从而使成品乙烯中的含量可以忽略不计。
Polyvinyl chloride (PVC) is manufactured by polymerizing (linking together) a chemical called polyvinyl chloride. Regulations strictly limit levels of polyvinyl chloride in the workplace and in emissions from manufacturing plants. Manufacturers convert as much polyvinyl chloride into PVC as possible to make maximum use of this raw material, then apply steam to strip out the remaining polyvinyl chloride so that levels in the finished vinyl are negligible.
