PVC is one of the oldest synthetic
materials with the longest history in industrial production. Its early history
is of multiple and accidental discovery in different places at different times
as well as unsuccessful quests for commercial application.
In 1913, German inventor Friedrich Heinrich
August Klatte took out a patent on PVC. His method used polymerization of vinyl
chloride with sunlight. The most significant breakthrough occurred in the
United States when the company BFGoodrich hired the industrial scientist Waldo
Semon to develop a synthetic replacement for the increasingly costly natural
rubber. His experiments again produced polyvinyl chloride. However, the
material was threatened by the recession in the 1920s and it was under threat
of abandonment that Semon conceived the idea of PVC as a water resistant
coating for fabrics. Sales took off quickly with a rapidly expanding product
range. Demand accelerated again during the Second World War, when PVC quickly
replaced traditional material to insulate wiring on military ships. PVC

During the 1950's many more companies
started to produce PVC and volumes increased dramatically around the world.
Developers quickly found further, innovative uses through the decade and
refined methods to enhance durability, opening the door to applications in the
building trades. By the middle of the 20th century, five companies were
producing PVC, and ground-breaking uses for PVC, or ‘vinyl’ as it is also
known, continued to be found during the 1960s. Vinyl-based latex was used on
inflatable structures and fabric coatings, and at the same time, methods for
improving PVC's durability were developed, allowing applications in the
building industry. buy pharmaceutical PVC film
PVC products rapidly became essential to
the construction industry; the plastic's resistance to light, chemicals and
corrosion made it the best option for building applications. Improvement made
to the materials’ resistance to extreme temperatures, allowed for PVC to be
transporting water to thousands of homes and industries. By the 1980s, twenty
companies were producing PVC. Today, PVC is the third largest-selling commodity
plastic in the world after polyethylene and polypropylene. PVC's low cost,
excellent durability and processability make it the material of choice for
dozens of industries such as health care, IT, transport, textiles and
construction. PVC sheets for folding box
