Polyvinyl Chloride (PVC) is among the most versatile plastics with a wide variety of end use applications; e.g., packaging articles and construction. Its availability in many rigid and flexible forms - both durable and light weight, clear or coloured - gives designers opportunities that they would not find in any other material. This, coupled with its continuous improvement, makes PVC an acceptable part of modern living.
