Rigid PVC

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
• Ease of processing
- Can be 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.
