Rigid P.V.C.

Rigid PVC (PolyVinylChloride)
(Industrial Grade)

Rigid PVC is one of the oldest thermoplastics in existence today. In 1912 German chemists F.Klatte and E.Zacharias were granted a patent for the process of manufacturing vinyl chloride monomer by addition of hydrogen chloride to acetylene, although full-scale production did not start until 1938. PVC is made up from carbon, hydrogen and approximately 50% by weight chlorine.

Rigid PVC or unplasticised PVC can be characterised by the following properties:

  • Low cost
  • Excellent chemical resistance
  • Good resistance to stress cracking
  • Good impact strength
  • Good weatherability
  • Flame retardant
  • Low coefficient of linear thermal expansion
  • Excellent electrical insulation
  • Easily machined
  • Can be hot formed
  • Can be welded
  • Suitable for hot shaping
  • Suitable for vacuum forming
  • Can be glued

Fields of application: acid and chemical storage tanks, extraction systems, chemical piping systems, meter boxes, cable ducting, cooling tower elements, photographic emulsion tanks and electrical insulators.
