Polyvinyl chloride

MFA Acc. #: L-SE 1057.1.2

Description

A colorless thermoplastic polymer made from vinyl chloride. Polyvinyl chloride (PVC) was discovered in 1838 Henri Regnault noticed a powder inside of a container of vinyl chloride. It was further studied in 1872 by Baumann and in 1912 by Ostromislensky, but was not commercialized until 1926, when a chemist at B.F.Goodrich, Waldo Semon, discovered a method to plasticize PVC into a soft rubbery material. The first moldable PVC, called Koroseal, was introduced in 1930. PVC is resistant to moisture but stabilizers are needed to prevent discoloration from light and heat. Lightly plasticized PVC has been used for gramophone records. Heavily plasticized PVC is used as a rubber substitute for thin sheeting, wire coverings, gaskets, tubing, raincoats, storage sleeves and fabric coatings. Phthalate plasticizers were commonly used in the middle of the 20th century for PVC plastics. However, these oily plasticizers tended to creep and separate with time producing an oily surface and leaving a brittle substrate so some more recent PVC formulations use copolymerization techniques for film modification rather than plasticizers. Rigid unplasticized PVC was introduced in 1958 in Europe as alternative piping for town water services to replace corroded iron pipes.

Hazards and Safety

Degrades with heat and light to darken and potentially produce hydrochloric acid. May also form carbon monoxide or phosgene. Plasticizers and stabilizers can continually ooze from polymer resulting in an oily film, white bloom, or corroded metal. Additionally some plasticizers are toxic. PVC is a suspected carcinogen.

Production and incineration of PVC can introduce toxic chlorinated organic chemicals into the environment (e.g. dioxin).
