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.
