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.

And also its structural integrity, In addition, it Rewards from possessing better color-fastness in comparison to option PVC foam products out there that you can buy.
Have in mind, PVC board is just not especially solid on its own, so it will require a base or guidance method to forestall bending or breaking.
PVC was synthesized in 1872 by German chemist Eugen Baumann soon after prolonged investigation and experimentation.[twelve] The polymer appeared being a white reliable within a flask of vinyl chloride that were still left over a shelf sheltered from sunlight for four weeks. While in the early 20th century, the Russian chemist Ivan Ostromislensky and Fritz Klatte on the German chemical business Griesheim-Elektron both tried to employ PVC in commercial items, but issues in processing the rigid, from time to time brittle polymer thwarted their attempts.
The molecular structure of PVC includes an extended-chain polymer with repeating vinyl chloride models. Every vinyl chloride unit has just one carbon atom double-bonded to the chlorine atom and one-bonded to 2 hydrogen atoms.
PVC is mainly manufactured being a rigid or unplasticized polymer (RPVC) or as a flexible plastic (uPVC). Flexible, plasticized or common PVC is softer and even more amenable to bending than pvc شبابيك uPVC due to the addition of plasticizers like phthalates for instance 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.
Since this content contains a easy area and absorbs and holds paint very well it causes it to be perfect for various applications. Expanded PVC might be painted with any plastic-friendly paint which incorporates most spray paints. Thermal Conductivity
Expanded PVC It is ideal as A part of upholstery, backings for seats, the base for seats, and other sections within your vessel. Here is the great substrate for boat seats, upholstery, and seating bases for the next causes:
Automotive: PVC is likewise found in the automotive sector for parts 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 två former:
The carbon-chlorine bonds within the vinyl chloride models give PVC its distinctive Houses, for example resistance to environmental variables and electrical insulation.
