Introduction to Polyvinyl Chloride (PVC)

Polyvinyl chloride, commonly known as PVC, is a widely used plastic. Its applications range from pipes to clothing, thanks to its versatility and cost-effectiveness.

PVC was accidentally discovered twice, first in 1835 by Henri Victor Regnault and later in 1872 by Eugen Baumann. Its practical uses were not realized until the early 20th century.

PVC is produced through polymerization of vinyl chloride monomer. Two methods are used: suspension and emulsion polymerization, with the former being the most common for its simplicity.

PVC is flame resistant, has high chemical stability, and offers excellent electrical insulation. These properties make it valuable in construction, healthcare, and electronics.

PVC's durability is a double-edged sword. While beneficial for long product lifespans, it poses significant environmental challenges due to its resistance to biodegradation.

PVC is recyclable and can be broken down into microplastics for reuse. However, the process is complex due to the presence of various additives.

Bio-based PVC is an emerging development, where ethylene is sourced from renewable materials. This innovation aims to reduce the environmental footprint of PVC production.
