パイプなどのように、断面形状がシンプルな形状の製品を作るのに適しています。口金の形状を変えることで、押し出される製品も形を変えられます。
Its commonest use is in the construction industry, but It is usually accustomed to manufacture signs, in healthcare programs, and as being a fiber for apparel.
Expanded marine PVC board or expanded PVC is actually a form of PVC that has been expanded using a Exclusive foaming agent to boost the thickness of the material even though decreasing its density. The foaming agent continues to be A part of the look purposefully to reduce exactly how much plastic is utilized.
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。
در مقابل حرارت و نور نسبتاً ناپایدار بوده و هیدروژن کلرید از آن خارج می‌شود. این ماده اثرات زیان‌بخشی روی خواص اشیاء دم دست (اجزای الکتریکی) علاوه بر اثرات فیزیولوژیکی بر جای می‌گذارد. پی‌وی‌سی پلاستیکی سخت است که به‌وسیلهٔ اضافه کردن روان‌کننده‌ها نرم و انعطاف‌پذیر می‌شود. بیشترین مورد استفادهٔ آن فتالیت است.

Automotive: PVC can be found in the automotive industry for pieces like dashboards, seat coverings, and insulation for wiring.
Poly(vinyl chloride) (PVC) has long been an interesting pvc شبابيك issue for polymer science analysis. 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 elemental limiting characteristics of PVC have been proposed to become alleviated by enhanced chemistry during PVC synthesis, Together with using each 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 past and most up-to-date investigate discoveries. It has been instructed that some of the basic restricting Qualities of PVC might be lessened by implementing the two inorganic and organic and natural thermal stabilizers in conjunction with improved chemistry through PVC manufacture.
Key intent of this undertaking should be to assist the public to discover some fascinating and crucial information regarding chemical features and many frequent resources. We know that the basic principles while in the elements science might help folks to be aware of many frequent difficulties.
PVC’s adaptable properties have led to its vast use in many sectors. Some popular applications consist of:
