2024年11月27日 · Poly(vinyl chloride) (PVC) has been a fascinating subject for polymer science research. Its characteristics are heightened by its inherent structural faults resulting from direct manufacturing (by free-radical polymerization), which also cause its thermal instability.

聚氯乙烯（Polyvinyl chloride)，英文简称PVC，是世界上产量第三大的合成聚合物塑料（仅次于聚乙烯和聚丙烯），每年生产大约4000万吨PVC。 PVC是氯乙烯单体（VCM）在过氧化物、偶氮化合物等引发剂或在光、热作用下按自由基聚合反应机理聚合而成的聚合物。

PVC is an inherently efficient polymer and a superior choice for a broad range of market applications. Whether you’re looking for extruded exterior products for fence, deck and rail or fire-retardant and low temp performance for wire and cable, with GEON, you’ll get the consistent, quality material you need to tackle the most pressing ...

Polyvinyl chloride (alternatively: poly (vinyl chloride), [6][7] colloquial: vinyl[8] or polyvinyl; abbreviated: PVC[8]) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year. [9]

Polyvinyl chloride ('PVC') is a high strength thermoplatic polymer. Vinyl chlorine monomer (‘VCM’) is the primary raw material used in the manufacture of polyvinyl chloride (‘PVC’) resins and is produced by the reaction of ethylene and chlorine, which produces EDC that is then transformed into VCM by thermal cracking.

2024年11月1日 · This study describes the chemical modification of PVC using different materials as an active modifying agent. The latter included substitutions, PVC modifications, nucleophilic radicals, removal or dehydrochlorination, and grafting polymerizations.

2021年10月3日 · PVC production has grown by about 4% per year since 1990. The largest growth is experi-enced in Asia (especially in China), followed by North America and Europe.6 There are four major methods of production of PVC, including bulk, emulsion, solution, and suspen-sion polymerizations. Suspension polymerization is the most common since it accounts

2024年8月22日 · 聚氯乙烯是氯乙烯单体（VCM）在过氧化物、偶氮化合物等引发剂存在下或在光、热作用下，按自由基聚合机理聚合而成的聚合物。 氯乙烯均聚物和氯乙烯共聚物统称为氯乙烯树脂。 PVC 曾是世界上产量最大的通用塑料，用途广泛。 PVC 有两种类型：硬质（有时缩写为 RPVC）和柔性。 硬质聚氯乙烯用于建筑管道、门窗。 它还用于制造塑料瓶、包装、银行卡或会员卡。 添加增塑剂可以使 PVC 更柔软、更柔韧。 它用于管道、电缆绝缘、地板、标志、唱片、 …

Polyvinyl chloride is a thermoplastics material which consists of PVC resin compounded with varying proportions of stabilisers, lubricants, fillers, pigments, plasticisers and processing aids. Different compounds of these ingredients have been developed to obtain specific groups of properties for different applications.
