در هر دو موقعیت پلیمر زمانی آشکار شد که جامد سفید رنگ داخل فلاسک وینیل کلراید در معرض نور آفتاب قرار گرفت.

در سال ۱۹۲۶ والدو سیمون از بی‌اف گودریچ روشی برای نرم کردن پی‌وی‌سی به‌وسیلهٔ مخلوط کردن آن با افزودنی‌های گوناگون گسترش داد. نتیجه ماده‌ای انعطاف‌پذیر بود که به سادگی در فرایندها شرکت می‌کرد و به سرعت در استفاده‌های تجاری شایع شد.
Irrespective of its environmental implications, attempts are underway to manage PVC squander by productive recycling mechanisms, pushing in the direction of a more sustainable use of this invaluable substance.
A further vastly effective assets of the maritime PVC foam board we feature here at Boat Outfitters is that it’s water and weatherproof.
ポリ塩化ビニルの「ポリ」という言葉は、ポリマー（重合体）からきたもので、「たくさん」という意味があります。しかし、一般的に呼ばれている「塩ビ」は塩化ビニルではなく、ポリ塩化ビニルを指しているケースが多いので注意が必要です。
型のなかにある空気を吸い取り、大気圧で型に押し付ける手法を「真空成形」、大気圧ではなく圧縮空気で金型に押し付ける手法を「圧空成形」と呼びます。
Untimely ventricular contractions frequently bring about few or no indicators. But the extra beats can result in unconventional sensations inside the upper body, like:
金属加工業界の未来を支える人材確保のカギとは？取り組みと課題を徹底解説

Poly(vinyl chloride) (PVC) has long been an interesting matter for polymer science research. Its attributes are heightened by its inherent structural faults resulting from immediate manufacturing (by cost-free-radical polymerization), which also cause its thermal instability. A number of the elemental limiting capabilities of PVC happen to be instructed to be alleviated by enhanced chemistry during PVC synthesis, As well as using the two inorganic and natural and organic thermal stabilizers. The qualities, characterization, modification, recycling, and many programs of PVC are all examined With this paper along with the previous and most recent investigation discoveries. It has been instructed that some of the basic restricting Qualities of PVC is often lessened by applying equally inorganic and natural and organic thermal stabilizers together with enhanced chemistry during PVC manufacture.
Packaging: PVC’s overall flexibility and resistance to oil and grease allow it to be a fantastic option for food packaging.
While PVC has a lot of advantageous uses, it also has an important environmental effects. The output and disposal of PVC may lead to the discharge ابواب وشبابيك pvc of damaging chemicals into the environment. On top of that, resulting from its toughness, PVC squander can persist inside the surroundings for extended durations.
