PVC clothing - Wikipedia

pvc clothing, commonly known as vinyl clothing, is shiny clothing made of the plastic polyvinyl chloride (pvc). The pvc plastic is also called vinyl. For this reason, this type of clothing is also called vinyl clothing. pvc is sometimes confused with the similarly shiny patent leather. The terms "pvc", "vinyl" and "PU" tend to be used interchangeably by retailers for clothing made from shiny plastic-coated fabrics. These fabrics usually consist of a backing woven from polyester fibers with a 

Vinyl chloride - Wikipedia

Vinyl chloride is an organochloride with the formula H2C=CHCl that is also called vinyl chloride monomer (VCM) or chloroethene. This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (pvc). About 13 billion kilograms are produced annually. VCM is among the top twenty largest petrochemicals (petroleum-derived chemicals) in world production. The United States currently remains the largest VCM manufacturing region 

PVC decking - Wikipedia

Disadvantages[edit]. Compared to other synthetic decking products, pvc is the most expensive. The 100% pvc makeup of the board makes it costlier than the wood powder/plastic mix used in composite decking. This cost means that pvc will be a more expensive investment up front, although manufacturers claim that the long life and low maintenance requirements of the deck make it an economical decision in the long run. pvc lacks the realistic feel of 

Plasticizer - Wikipedia

Over the last 60 years more than 30,000 different substances have been evaluated for their plasticizing properties. Of these, only a small number – approximately 50 – are today in commercial use. The dominant applications are for plastics, especially polyvinyl chloride (pvc). The properties of other materials are also improved when blended with plasticizers including concrete, clays, and related products. According to 2014 data, the total global market for plasticizers was 8.4 million 

Plastic bottle - Wikipedia

Plastic bottles were first used commercially in 1947 but remained relatively expensive until the early 1950s when high-density polyethylene was introduced. They quickly became popular with both manufacturers and customers due to their lightweight nature and relatively low production and transportation costs compared with glass bottles. However, the biggest advantage plastic bottles have over glass is their superior resistance to breakage, in both production and transportation.

Plastic recycling - Wikipedia

Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products. Since the vast majority of plastic is non-biodegradable, recycling is a part of global efforts to reduce plastic in the waste stream, especially the approximately eight million tonnes of waste plastic that enter the Earth's ocean every year. This helps to reduce the high rates of plastic pollution. Plastic recycling includes taking any type of plastic, sorting it into different 

Plastic - Wikipedia

Generic term used in the case of polymeric material that may contain other substances to improve performance or reduce costs. Note 1: The use of this term instead of polymer is a source of confusion and thus is not recommended. Note 2: This term is used in polymer engineering for materials often compounded that can be processed by flow. Plastic is material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded 

Blister pack - Wikipedia

The most basic material for the forming web is polyvinyl chloride (pvc). The principal advantages of pvc are the low cost and the ease of thermoforming. The main disadvantages are the poor barrier against moisture ingress and oxygen ingress. In the case of blister packaging the pvc sheet does not contain any plasticizer and is sometimes referred to as Rigid pvc or Rpvc. In the absence of plasticizers, pvc blisters offer structural rigidity and physical protection 

Wood-plastic composite - Wikipedia

Wood-plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials. WPCs are a subset of a larger category of materials called natural fiber plastic composites (NFPCs), which may contain no cellulose-based fiber fillers such as pulp fibers, peanut hulls, bamboo, straw, 

Closed-cell PVC foamboard - Wikipedia

Closed-cell pvc foamboard is a lightweight rigid material used primarily in the manufacture of signs and displays. It is considered robust for outdoor use, being immune to rain and resistant to wind and sunlight. Contents. [hide]. 1 History; 2 Processing; 3 Properties; 4 Common uses; 5 Issues; 6 References. History[edit]. In 1912, the first patents for pvc were founded in Britain and Germany. It was not until the early 1930s that pvc was able to be produced cheaply, limiting its 

Plastic welding - Wikipedia

Plastic welding is welding for semi-finished plastic materials, and is described in ISO 472 as a process of uniting softened surfaces of materials, generally with the aid of heat (except solvent welding). Welding of thermoplastics is accomplished in three sequential stages, namely surface preparation, application of heat and pressure, and cooling. Numerous welding methods have been developed for the joining of semi-finished plastic materials. Based on the mechanism of heat 

Virtual circuit - Wikipedia

A virtual circuit (VC) is a means of transporting data over a packet switched computer network in such a way that it appears as though there is a dedicated physical layer link between the source and destination end systems of this data. The term virtual circuit is synonymous with virtual connection and virtual channel. Before a connection or virtual circuit may be used, it has to be established, between two or more nodes or software applications, by configuring the relevant parts of the 

Engineering plastic - Wikipedia

Engineering plastics are a group of plastic materials that have better mechanical and/or thermal properties than the more widely used commodity plastics Being more expensive, engineering plastics are produced in lower quantities and tend to be used for smaller objects or low-volume applications (such as mechanical parts), rather than for bulk and high-volume ends (like containers and packaging). The term usually refers to thermoplastic materials rather than thermosetting ones.
