PVC is produced from the polymerisation of Vinyl Chloride Monomer (VCM). It is a versatile thermoplastic with a wide range of uses including pipes & fittings, profiles, cables, flooring, films & sheets. At least 50% of the market is driven by the construction/housing industry.
PVC is stable under normal temperatures and pressures but above 80 deg C the resin discolours and evolves hydrogen chloride. Repeated exposure to PVC dust can lead to skin irritation, dermatitis and conjunctivitis. Freshly manufactured PVC can contain traces of toxic VCM, a confirmed human carcinogen. Some progress has been made in reducing the levels of residual VCM in PVC.
