聚氯乙烯(Polyvinyl chloride,简称PVC)是氯乙烯单体(vinyl chloride monomer, 简称VCM)在引发剂作用下聚合而成的热塑性树脂。 当前聚氯乙烯在五大通用树脂中使用量居第二位。2019年中国PVC有产能约2500万吨,实际生产2000万吨,与当年消费量持平。 聚氯乙烯广泛应用于管材、型材、薄膜、电线电缆、地板革等,主要用于与房...
The meaning of POLYVINYL CHLORIDE is a polymer of vinyl chloride used especially for electrical insulation, films, and pipes —abbreviation PVC.
PVCis knownas ‘Vinyl’ or "Polyvinyl Chloride". Its chemical formula is (C2H3Cl)n and it's insoluble in water and alcohol. In Europe, ‘Vinyl’ usually refers to certain specific flexible applications. For instance, flooring, decorative sheets, and artificial leather. ...
aPolyvinyl chloride was accidentally discovered on at least two different occasions in the 19th century first in 1853 by Henri Victor Regnault and in 1872 by Eugen Baumann. On both occasions the polymer appeared as a white solid inside flask of vinyl chloride that has been left exposed to sunli...
