همچنین محصولات فرعی وجود دارد که پروفیل‌های اکسترود شده بر پایهٔ پلی‌وینیل کلراید سخت (یو پی‌وی‌سی) با مقاومت ضربهٔ بالا و سطح خارجی سفید هستند و در ساخت در و پنجره‌هایی که در دیوارهٔ خارجی ساختمان به‌کار می‌روند، استفاده می‌گردند.
کلندرها: جهت تهیهٔ ورقه‌های طویل از کائوچو و ترموپلاستیک‌ها رزین نرم شده را بین دو یا چند سیلندر عبور می‌دهند.
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。
The polymers are linear and are robust. The monomers are largely organized head-to-tail, which means that chloride is found on alternating carbon centres. PVC has predominantly an atactic stereochemistry, which suggests that the relative stereochemistry of your chloride centres are random. Some degree of syndiotacticity on the chain presents a few % crystallinity that is certainly influential over the properties of the material.
Expanded marine PVC board or expanded PVC is actually a form of PVC which has been expanded with a Particular foaming agent to improve the thickness of the material although reducing its density. The foaming agent is A part of the look purposefully to reduce just how much plastic is utilised.

کارت‌های پی‌وی‌سی کارت‌هایی هستند که از پلاستیک فشرده تهیه شده و یکی از محصولات صنعت پتروشیمی هستند و مقاومت آن‌ها در مقابل گرما و سرما در مقایسه با کارت‌های کاغذی بسیار بالاتر بوده و دوام و ماندگاری آن نیز به دلیل نوع مواد به کار رفته در آن‌ها بیشتر است و بر اثر فشار یا ضربه آسیب نمی‌بینند.
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
با وجود این در آمریکا بیشتر کمپانی‌ها به‌طور اختیاری اسباب‌بازی‌های ساخته شده با پی‌وی‌سی برای نوزادان را متوقف کردند.
Indeed. An expanded PVC sheet has been intended with interior and exterior uses in your mind. You are able to hence utilize it with self-assurance on exterior features of your respective boat that may be subjected to rain, snow, sleet, as well as other adverse climatic conditions. Can expanded marine PVC board be bent to condition?(demonstrate/hide)
Poly(vinyl chloride) (PVC) continues to be a fascinating subject matter for polymer science research. Its features are heightened by its inherent structural faults resulting from immediate producing (by free of charge-radical polymerization), which also bring about its thermal instability. A few of the elemental limiting characteristics of PVC have been proposed to be alleviated by improved chemistry all through PVC synthesis, As well as using each inorganic and organic and natural thermal stabilizers. The traits, characterization, modification, recycling, and several purposes of PVC are all examined Within this paper together with the previous and most up-to-date exploration discoveries. It's been advised that several of the fundamental limiting Attributes of PVC may be lessened by making use of both inorganic and natural thermal stabilizers at the side of improved chemistry through PVC manufacture.
Upcoming, the alerts get there at a cluster of cells known as the atrioventricular (AV) node, exactly where they slow down. This slight hold off makes it possible for the ventricles to fill with blood. If the electrical alerts reach the ventricles, the chambers agreement and pump blood into the lungs or to the remainder of the physique.
Uncovered while in the nineteenth century, this long lasting product pvc شبابيك has observed purposes inside of a wide spectrum of industries as a consequence of its versatility, chemical stability, and financial efficiency.
