Pvc Sg3
IntroductionPVC is a thermoplastic resin, which in versatility of processing and application surpasses all other thermoplastic materials. This unique polymer is one of the oldest established plastics. ApplicationPVC finds applications in insulation of cables, in pipes and hoses, agricultural products, windows and profiles, flooring tiles used in the building industry, blister packaging, films and sheets, foamed leather cloth, curtains, tarpaulins, and also for medical use – for IV, blood bags, etc. The universality of its service properties is such that new areas of application are being continuously developed.
