PVC är ett vitt pulver som saknar lukt och smak. Smälts pulvret bildar det en styv färglös polymer med densiteten cirka 1400 kg/m³ och med en mjukningstemperatur vid cirka 82°C.
Community keep price ranges may perhaps differ from All those shown. Products and solutions revealed as out there are Commonly stocked but stock stages can't be assured.
And its structural integrity, What's more, it Positive aspects from possessing higher coloration-fastness as compared to different PVC foam items accessible out there.
Even with its environmental implications, endeavours are underway to control PVC waste by way of economical recycling mechanisms, pushing in direction of a far more sustainable use of this priceless product.
The contents on the response vessel are pressurized and regularly combined to keep up the suspension and be certain a uniform particle size from the PVC resin. The response is exothermic and therefore demands cooling. As the amount is decreased in the course of the reaction (PVC is denser than VCM), drinking water is frequently extra into the mixture to take care of the suspension.[9]
پلی‌وینیل کلراید به‌طور اتفاقی در دو موقعیت کوچک در قرن ۱۹ کشف شد. نخستین بار در سال ۱۸۳۵ به‌وسیله هنری ویکتور رگنالت و در ۱۸۷۲ به‌وسیله اوگن بومان.
PVC is primarily generated like a rigid or unplasticized polymer (RPVC) or as a flexible plastic (uPVC). Versatile, plasticized or normal PVC is softer and much more amenable to bending than uPVC mainly because of the addition of plasticizers like phthalates for example diisononyl phthalate or DINP.

Since this content provides a sleek surface and absorbs and holds paint very well pvc شبابيك it can make it perfect for many different apps. Expanded PVC is usually painted with any plastic-friendly paint which includes most spray paints. Thermal Conductivity
Allt eftersom biltillverkarna har sökt efter lättare content har fler och fler detaljer i bilen blivit tillverkade i plast.
Emulsion Polymerization: In this technique, vinyl chloride monomers are emulsified in drinking water with the assistance of surfactants. The polymerization reaction is then initiated by totally free radicals.
همچنین ماده‌ایست که اغلب برای لوله‌کشی آب و فاضلاب به علت ارزان بودن طبیعی و انعطاف‌پذیر بودن استفاده می‌شود.
モノマーである塩化ビニル（クロロエチレン）を、繰り返し結合したものをポリ塩化ビニルと呼びます。
The carbon-chlorine bonds inside the vinyl chloride units give PVC its distinct Homes, including resistance to environmental aspects and electrical insulation.
