UV-ljus och temperatur anses vara de faktorer som svarar fileör den huvudsakliga nedbrytningen vid utomhusåldring av plast. I likhet med andra plaster bryts PVC ned av solljus. Den fotokemiska nedbrytningen accelereras vid höjd temperatur.

Vid temperaturer upp till 60°C är styv PVC resistent mot de flesta oorganiska vätskor inklusive moderat koncentrerade syror samt alkali och icke-oxiderande saltlösningar i alla koncentrationer.
Consider, PVC board just isn't particularly sturdy on its own, so it will need a foundation or assistance process to stop bending or breaking.
PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimentation.[12] The polymer appeared as being a white strong inside a flask of vinyl chloride that were still left over a shelf sheltered from daylight for 4 months. From the early twentieth century, the Russian chemist Ivan Ostromislensky and Fritz Klatte with the German chemical corporation Griesheim-Elektron both of those tried to employ PVC in professional products and solutions, but difficulties in processing the rigid, sometimes brittle polymer thwarted their efforts.
The molecular framework of PVC includes a long-chain polymer with repeating vinyl chloride models. Each individual vinyl chloride device includes 1 carbon atom double-bonded to a chlorine atom and single-bonded to 2 hydrogen atoms.
PVC is mainly manufactured being a rigid or unplasticized polymer (RPVC) or as a flexible plastic (uPVC). pvc شبابيك Adaptable, plasticized or typical PVC is softer and more amenable to bending than uPVC because of the addition of plasticizers like phthalates which include diisononyl phthalate or DINP.
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.
Given that this product includes a sleek surface area and absorbs and retains paint well it makes it ideal for various purposes. Expanded PVC may be painted with any plastic-pleasant paint which incorporates most spray paints. Thermal Conductivity
Expanded PVC It is ideal as part of upholstery, backings for seats, The bottom for seats, and various sections of your respective vessel. This can be the excellent substrate for boat seats, upholstery, and seating bases for the next causes:
Automotive: PVC can also be located in the automotive sector for components like dashboards, seat coverings, and insulation for wiring.
همچنین ماده‌ایست که اغلب برای لوله‌کشی آب و فاضلاب به علت ارزان بودن طبیعی و انعطاف‌پذیر بودن استفاده می‌شود.
PVC tillverkas genom kedjepolymerisation av vinylkloridmolekyler och kan efter användningsområden indelas i Televisionå previous:
・価格が安価：他の材質に比べて価格が安価。重量も重たくないので、運送費や管理費なども抑えられる。
