Polyvinyl chloride or PVC was discovered in the 1800s and was plasticized in 1935. Also known as vinyl, PVC was a popular plastic polymer until polypropylene was developed in the 1950s as a safer, environmentally friendly alternative.
PVC Vinyl vs. Polypropylene
Propylene is one of the most neutral plastics, containing only two elements, carbon and hydrogen. PVC vinyl by comparison contains approximately 30% by weight of the element chlorine in its basic structure. It is well documented that chlorine, like all halogens, is a dangerous substance in the environment. When PVC is burned, it produces toxic byproducts such as dioxins, chlorocarbons and hydrochloric acid. In addition, PVC has limited recyclability because of its' chemical composition and the incorporation of numerous additives. The burning of polypropylene, in comparison, generates only carbon dioxide and water.
