Description
Polyvinyl Chloride or PVC is the most practical synthetic plastic polymer after polyethylene and polypropylene. PVC is produced in two different forms. It can be rigid which is called RPVC and used in pipes and profiles like doors and windows. It also can be made more flexible to be used in flooring, signage, plumbing, electrical cable insulation ….
PVC’s hardness is high. Its mechanical properties increase by the molecular weight increase and it will decrease by the temperature increase. Since the row PVC’s stability in heat is poor, it is necessary to use heat stabilizer during the thermal processes. Adding enough amount of stabilizer can increase the melting temperature of the PVC up to 260°C (500° F).
PVC can be suitable to be used for insolation of medium or low voltage materials. As PVC is resistant to different chemical substances like acids, salts, bases, fats and alcohols, it will be resistant to corrosive effects of sewage and can be used in sewage piping networks.
PVC is one of the most used materials in cities water and sewage networks. It is used in building industry as window frames and flooring materials. Its plasticized form is used as insulation on electrical cables. Also it can be used as a weather resistant material in clothing industry to make coats, jackets, skiing equipment, shoes and sport bags.
