UV-ljus och temperatur anses vara de faktorer som svarar för den huvudsakliga nedbrytningen vid utomhusåldring av plast. I likhet med andra plaster bryts PVC ned av solljus. Den fotokemiska nedbrytningen accelereras vid höjd temperatur.
دستگاههای ژلیفیکاسیون: معمولاً از نوع ماشینهای تهیهٔ ورقه هستند.
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.
As the fabric might be Slash into various styles and sizes, it can be used for tailor made signs or areas.
塩ビは耐久性・耐薬品性・電気絶縁性などに優れている特徴から、幅広い用途で採用されています。建築資材で使われることの多い材料のため、塩ビの取扱いがない方でも目にする機会は多くあります。
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。

Automotive: PVC can also be located in the automotive business for pieces like dashboards, seat coverings, and insulation for wiring.
Poly(vinyl chloride) (PVC) continues to be an interesting subject for polymer science investigation. Its characteristics are heightened by its inherent structural faults resulting from immediate manufacturing (by absolutely free-radical polymerization), which also trigger its thermal instability. Several of the fundamental limiting options of PVC have already been instructed to become alleviated by enhanced chemistry all through PVC synthesis, As well as using both inorganic and organic and natural thermal stabilizers. The characteristics, characterization, modification, recycling, and a variety of purposes of PVC are all examined On this paper together with the earlier and most recent investigate discoveries. It has been proposed that some of the basic restricting Homes of PVC is often lessened by applying the two inorganic and organic and natural thermal stabilizers along side improved chemistry in the course of PVC manufacture.
Packaging: PVC’s flexibility and resistance to oil and grease allow it to be a fantastic option for food stuff packaging.
Untimely ventricular contractions (PVCs) are excess heartbeats that get started in among the coronary heart's two decrease pumping chambers (ventricles). These further beats disrupt the normal coronary heart rhythm, at times causing a feeling of a fluttering or possibly a skipped beat شباك pvc from the chest.
