Unplasticized polyvinyl chloride UPVC

Polyvinyl chloride is processed into a number of forms by including additives. Additives are used to vary the properties of PVC so that it can be made soft and flexible or hard and rigid. Additives are also used to inhibit decomposition as a result of exposure to sunlight, ozone, and chemicals. Plasticizers are the primary additive included in PVC materials. Di(2-ethylhexyl) phthalate (DEHP) and a host of other phthalates are the most common plasticizers. Plasticizers impart flexibility, thermal stability, strength, and resilience to PVC compounds. PVCs without plasticizers are classified as UPVC the letters stand for unplasticized polyvinyl chloride. UPVC is rigid and used for conduit, containers, gutters, and floor tiles. Other common PVC additives are biocides, lubricants, and pigments. 

Unplasticized polyvinyl chloride (uPVC) is a commonly used material for mains and domestic potable water piping. The additives used in uPVC include heat stabilizers to reduce decomposition of the uPVC during manufacture. Stabilizers are often lead salts. It has been shown that leaching of lead can occur, but this seems to be significant only for new uPVC pipes (Packham, 1971 Poels and Dibbets, 1982). In some countries (e.g. France) the application of lead salts as stabilizers is not allowed. 

It was soon found that many polymers with poor weathering properties could be transformed by compounding with stabilizers such as antioxidants, UV agents, carbon black, and so on, into materials which were suitable for external use, well-known examples being synthetic rubbers, unplasticized polyvinyl chloride (UPVC) and polypropylene. 

Unplasticized polyvinyl chloride (uPVC) Polyvinyl chloride (PVC) that does not contain plasticizers that can migrate to the surface and become a source of contamination. Tubing of the material is used to distribute ultrapure water. Also used as a material in contact with a clean surface.
