Polyvinyl chloride (PVC) est unus de maxime solebat thermoplastic polymers in mundo (deinde ad tantum pauci magis late usus plastics sicut pet et Pp). Est naturaliter albus et valde fragile (prior ad additum plasticizers) plastic. PVC fuit circa iam quam maxime plastics fuisse primum synthesized in MDCCCLXXII et commercium produci ab BF Goodrich Company in 1920s. Per comparationem, multis aliis communi plastics primum synthesized et factus commercium viable in 1940s et 1950. Hoc est usus maxime communiter in constructione industria sed etiam propter signa, curis applications, et sicut fibra in vestimentis.
PVC est produci in duas generales formas, prius quam rigidum aut unplasticized polymer (RPVC et UPVC), et secundum quod flexibilia plastic. Flexibile, plasticized et iusto PVC est mollior et magis amenable ad flexuram quam Upvc debitum ad additionem plasticizers sicut phthalates (eg Disononyl Phthalate et Dinp). Flexible PVC is commonly used in construction as insulation on electrical wires or in flooring for homes, hospitals, schools, and other areas where a sterile environment is a priority, and in some cases as a replacement for rubber.
Rigidorum PVC est etiam in constructione ut pipe ad plumbing et in faveo quod communiter referred to a terminus "Vinyl" in Civitatibus Foederatis Americae. PVC pipe est saepe referred to a "schedule" (eg schedule XL vel schedule LXXX). Maior differentias inter cedulas includit quae quasi murum crassitudine, pressura rating et colore.
Quidam de PVC plastic scriptor maxime momenti proprietatibus includit suum relative humilis pretium, ad resistentiam ad environmental degradation (tum ut chemicals et alkalies), princeps duritiam et praestantes PVC vires ad plastic in casu et outstanding PVC fortitudinem ad plastic in casu et outstanding PVC fortitudinem ad plastic in casu et outstanding PVC vires. Est late praesto, communiter usus et facilius recyclable (geno resinatis idem codice "III").
