Abbreviation for polyvinyl chloride; one of the most commonly used plastics. Chlorine and ethylene are the most important starting materials for its production. The material is weatherproof, flame-retardant and corrosion-resistant, as well as resistant to alcohol, petrol, alkalis, oil and acids. It is mainly used in the building materials industry (floor coverings, window frames), as well as for packaging and for the production of beverage bottles. PVC is also used in viticulture for various materials such as containers, tubes and closures (e.g. capsules). In order to obtain the desired properties, various agents such as stabilizers, paints, plasticizers, fillers, etc. are added to the raw PVC. Therefore PVC is not undisputed. A number of ecological problems also arise during production, so that other substances are increasingly being used. See also polyethylene (PE) and PVDC.
