Polivinil klorür, (genelde kısaltılmış olarak PVC diye kullanılır) oldukça geniş kullanım alanı olan bir plastik. Kimyasal endüstrisinde en değerli ürünlerden biridir. Dünyada PVC’nin % 50’den fazlası yapı sektöründe kullanılır. Bina malzemesi olarak, PVC ucuz ve kolay monte edilebilirdir. Son yıllarda, PVC geleneksel yapı malzemeleri olan ahşap, beton ve kılın birçok alanda yerini almıştır. İdeal yapı malzemesi olmasına rağmen, çevre ve insan sağlığı için PVC hakkında kaygılar vardır
PVC is a plastic material that is used for many purposes, for example to make clothing or shoes or to cover chairs. PVC is an abbreviation for `polyvinyl chloride'. a type of plastic, used to make pipes, window frames, clothes etc (polyvinyl chloride). in full polyvinyl chloride Synthetic resin, an organic polymer made by treating vinyl chloride monomers with a peroxide. It may be blended with more rubbery polymers or copolymerized with other vinyls to obtain products with desired properties. PVC resin mixed with plasticizers (see Waldo Semon), stabilizers, and pigments is made into flexible articles (e.g., raincoats, toys, containers). Nonplasticized resin has been used for rigid products (e.g., water pipes, plumbing fittings, phonograph records). Concern over leaching of vinyl chloride into foods has resulted in restrictions on its use in food containers; its decomposition into hydrogen chloride when burned has also raised concerns. Today it is produced in larger quantities than any other plastic except polyethylene
Polyvinyl Chloride A plastic plumbing material, typically white or black, used primarily for yard service pipe, outdoor irrigation systems or interior drain, waste and vent systems
Permanent Virtual Connection A logical path that is software defined in a public network by a carrier within a packet-switched network such as Frame Relay The actual pathway through the packet-switched network may change due to routing around downed or busy connections, providing advantages over a simple point to point data circuit which has no routing ability to avoid congestion
Polyvinyl Chloride (PVC) is the plastic material used in the manufacture of laminated card bodies
Polyvinyl chloride, a plastic generally considered unsafe by ISO for use with photographs due to its plasticizer content and potential for emission of hydrochloric acid upon its degradation Note that PVC comes in both flexible and rigid forms The harmful plasticizer is used only in the flexible form
Permanent Virtual Circuit or Connection Virtual circuit that is permanently established PVCs save bandwidth associated with circuit establishment and tear down in situations where certain virtual circuits must exist all the time In ATM terminology, called a permanent virtual connection Compare with SVC See also virtual circuit
A type of plastic (polyvinyl chloride) suitable for drain and cold water applications
Permanent Virtual Circuits PVC's contrast with Switched Virtual Circuits (SVC) A connection to a network that allows connection and disconnection to various points is a switched virtual circuit Circuits that are routed through software switching devices like X 25 pads and frame relay networks are virtual A hard wired connected in a plain old circuit, not a virtual circuit
Polyvinyl chloride, a polymer of vinyl chloride used to make a diverse range of cost-effective products with various levels of technical performance suited to a wide range of applications Many of these PVC products are used everyday and include everything from medical devices such as medical tubing and blood bags, to footwear, electrical cables; packaging, stationery, and toys
Polyvinylchloride, the plastic most commonly used for credit/debit cards; less expensive but shorter life than polyester; can be embossed and requires lower laminating temperatures
