More commonly known by the abbreviation as PVC, polyvinyl chloride is the third largest thermoplastic polymer used in the market. One of the most valuable products of the chemical industry is PVC, it is used in many areas like toys and building construction industry .
PVC production is done in the industry with more suspension polymerization method. This polymer has a low crystalline structure, which consists the vinyl chloride. Despite low crystallinity, it generates large volumes of chlorine through big chlorin groups in the chain and thereby is such resistant material. Chlorine groups’ influence to chain flexibility (or rather rigidity to) can be seen from glazing temperature (Tg = 80 ° C).
One of the bigggest problem of PVC is to be sensitive to light and heat. Because of unstable structure, when exposed to high temperature or light for long hours, it sends out hydrogen chloride (HCl) and causes to fizzle the other material in environment. More importantly, HCl is harmful for human health. PVC or haloid polymers like PVC are stabilized with additives and reduced to bring hazardous waste or eradicated completely.
PVC is a very hard and tough material and thanks to these mechanical features it has wide usage area. Moreover, since the start of use of plasticiser additives to make PVC flexible, it has become more important in the market. To increase the impact strength of PVC, PVC plastic is mixed with the rubber.
Resistant It can be shaped by heat. It has smooth surface. Resistant for bacteria texture. Its electricity isolation is superior.It doesn't contain the heat within itself.
