Polyvinyl chloride (colloquial: polyvinyl, vinyl; abbreviated: PVC) is the world's third-most widely produced synthetic plastic polymer (after polyethylene and polypropylene).About 40 million tons of PVC are produced each year. PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible.

Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer. The amount of ...

A plasticizer (UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, or to decrease friction during its handling in manufacture.. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the raw material during fabrication, or to meet the ...

Esters made with C4 or C5 alcohols produce plasticizers with high-volatile losses, while phthalate esters made from alcohols with carbon numbers greater than C13 are not compatible with PVC. Performance of the plasticizer can vary greatly with changes in carbon number.

Polyvinyl Chloride (PVC) is one of the most widely used polymers in the world. Due to its versatile nature, PVC is used extensively across a broad range of industrial, technical and everyday applications including widespread use in building, transport, packaging, electrical/electronic and healthcare applications.

No liquid plasticizer. Test results on an array of PVC compounds containing 20% to 35% POE and 0 to 60 phr of liquid plasticizer were presented by Vishal Kadakia, product-development engineer, at the Society of Plastics Engineers' Vinyltec 2001 conference in Iselin, N.J., last September.

Modern plasticisers (US: plasticizers) are similar and different at the same time – constituting a wide range of chemistries and molecules bringing high performance in a wide array of applications in a safe and sustainable manner. They are colourless and odourless liquids which cannot be simply treated as additives like pigments or fillers.

Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available.. Polyurethane polymers are traditionally and most commonly formed by reacting a di- or triisocyanate with a polyol.Since polyurethanes contain two types of ...
