Vid temperaturer upp till sixty°C är styv PVC resistent mot de flesta oorganiska vätskor inklusive moderat koncentrerade syror samt alkali och icke-oxiderande saltlösningar i alla koncentrationer.
立体的な製品を成形可能で、押し出し成形よりも複雑な形状を生産できます。製品のサイズも小さいものから大きなものまで対応が可能です。
PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimentation.[12] The polymer appeared as being a white sound within a flask of vinyl chloride that had been still left on the shelf sheltered from sunlight for four months. During the early twentieth century, the Russian chemist Ivan Ostromislensky and Fritz Klatte of your German chemical company Griesheim-Elektron both attempted to use PVC in commercial goods, but issues in processing the rigid, occasionally brittle polymer thwarted their efforts.

用途としては、上下水道管や波板などの建築資材や、家具のレザーなどに採用されており、私たちの身近なところでも、比較的見かけることが多いでしょう。
با وجود این‌که محصولات پی‌وی‌سی تولید شده‌اند یکی از بیشترین مواد سمی شیمیایی به نام دی‌اکسین را منتشر می‌کنند. محصولات پی‌وی‌سی زمانی‌که می‌سوزند یا دفن می‌شوند می‌توانند مضرانه نفوذ کنند.

Emulsion Polymerization: In this process, vinyl chloride monomers are emulsified in water with the assistance of surfactants. The polymerization reaction is then initiated by free radicals.
Poly(vinyl chloride) (PVC) has become a fascinating matter for polymer science investigate. Its qualities are heightened by its inherent structural faults ensuing from direct production (by free-radical polymerization), which also lead to its thermal instability. Many of the basic restricting attributes of PVC have been suggested for being alleviated by enhanced chemistry for the duration of PVC synthesis, in addition to the usage of both of those inorganic and natural thermal stabilizers. The features, characterization, modification, recycling, and numerous apps of PVC are all examined in this paper combined with the earlier and most recent investigate discoveries. It's been instructed that many of the elemental restricting Homes of PVC could be lessened by making use of both inorganic and organic and natural thermal stabilizers in conjunction with improved chemistry all through PVC manufacture.
