Plastics are also called synthetic resins and are broadly classified into two categories: thermosetting resins and thermoplastic resins.
The thermosetting resins include phenolic resin and melamine resin, which are thermally hardened and never become soft again. Thermoplastic resins include PVC, polyethylene (PE), polystyrene (PS) and polypropylene (PP), which can be re-softened by heating.
Usually, thermoplastics are supplied in the form of pelletised material (compounds) with additives (antioxidants, etc.) already blended in it. However, PVC resin is often supplied in powder form and long term storage is possible since the material is resistant to oxidation and degradation. Various additives and pigments are added to PVC during the processing stage, and the blend is then converted into PVC products.
PVC is sometimes known as Vinyl in Europe and predominantly so in North America. In Europe, Vinyl usually refers to certain specific flexible applications, such as flooring, decorative sheets and artificial leather.
PVC is a thermoplastic made of 57% chlorine (derived from industrial grade salt) and 43% carbon (derived predominantly from oil / gas via ethylene). It is less dependent than other polymers on crude oil or natural gas, which are nonrenewable, and hence can be regarded as a natural resource saving plastic, in contrast to plastics such as PE, PP, PET and PS, which are totally dependent on oil or gas. This chlorine gives to PVC excellent fire resistance.
For very specificqueries about PVC sustainability and regulations; and general information.
A confirmation that PVC can integrate high technical performance, environmental benefits, as well as cost advantages comes from a study conducted in three key application areas: windows frames, flooring and piping.
PVC industry delegates in Cascais (April 2012) agreed on the fact Innovation has been identified as the fundamental driving force to increase competitiveness and progress toward sustainability.
Building upon the achievement of Vinyl 2010, the European PVC industry has launched VinylPlus.
