Polyvinyl chloride (PVC) has the structural formula [-CH2-CHCl-] n with an average molecular weight of 10,000 to 100,000 and a chlorine content of about 57%.
It is obtained from the polymerization of vinyl chloride monomer: Vinyl chloride – polymerization – vinyl chloride polychloride
Polyvinyl chloride (PVC) – A thermoplastic material composed of polyvinyl chloride polymers. PVC is a colorless solid with outstanding resistance to water, alcohols, as well as concentrated and alkali acids.
Depending on the polymerization system, PVC types are different: (e) emulsion, (s) suspension, (m) mass, (sp) special and, depending on use: (g) general use and (p) .
The polymer is usually delivered as powder (seldom pearls for special applications), unstabilized. Finishing is done in heat, which causes degradation of the unstabilized polymer – release of chlorine, HCl, color change etc. – as a consequence, mandatory addition of stabilizing agents. Also added to the training compounds are various other additives such as: plasticizers, lubricants, dyes, fillers, etc., which allows to obtain a large variety of products with multiple properties
