PVC U was discovered in Germany in 1930 (Rigid Polyvinyl Chloride – no plastic coated). It is obtained by the polymerisation of vinyl chloride monomer. PVC is one of the most cheap, versatil and widespread plastic material. It can be used in several applications; through the addition of plasticizer agents, it can be shaped at will by hot moulding; it also offers a good chemical resistance and a not bad mechanical rigidity that decreases gradually as temperature increases, however it resists up to 60° C. Rigid PVC is one of the cheapest solution for the transport of corrosive indutrial liquids and for the water distribution / treatment. PVC resists to acids, alcohol, salts and paraffinic / aliphatic hydrocarbon. It is not suitable for the transport of polar organic compounds and for chlorinated and aromatic solvents. PVC can be reduced to a film or to the liquid state; the liquid PVC can be used to cover surfaces, valves, taps, tanks, artificial textile fibres and tissues. Rigid PVC presents a high combution resistance, fire triggers at 399° C and it persists in extreme conditions only: if the Oxygen concentration is twice as high as the atmospheric one or is flames are caused by an external source. Rigid PVC has an amorphous structure, it presents high solidity as well as high tensile modulus. It has excellent electrical features, especially at low voltage and frequencies. It can be used at temperature between – 10° C and + 60°C. Rigid PVC is physiologically inert and its suitability in food industry depends on the type of stabilisation. Rigid PVC is a good electrical isolating and it absorbs little water. Rigid PVC can be welded or sticked.

Protection - Because of liquids, gas and vapors repellency, rigid PVC is suitable for food and drugs packaging.
Stability - rigid PVC is phisiologically inert and stable so it is suitable for sectors in which hygiene is a priprity such as in the medical one. In accordance with European Pharmacopeia, PVC films can be used for making surgical gloves, blood bags and transfusion kits.
Longevity - PVC products are extremely durable, their life goes from 15 to 100 years if used in producing of electric cords, tubes and profiles for windows.
Security - Fire and chemical agents resistant as well as isolation properties make rigid PVC a material really suitable for using in buiding and industry sectors and in producing electric cords.

Application fields

Mechanical, chemical, electrical fields. Largely used in making of tanks for industrial machineries, fume hoods, gears, exhaust and drainage pipes, reinforced pipes, wastewater treatment plants.


  • Lower thermal resistance than PE an PP (max 60°C)
  • Low impact resistance
  • The high specific gravity affects the affordability
