As the most widely used and most productive industrial raw material PVC in the world, it is necessary for you to understand the development history of PVC. PVC was discovered by V. Lenio in 1835. PVC was discovered twice in the 19th century, once in 1835 by Henri Victor Regnault and the other in 1872 by Eugen Baumann. In 1912, Fritz Klatte, a German, synthesized PVC and applied for a patent in Germany. PVC was industrialized in the early 1930s. Since the 1930s, for a long time, the output of PVC has been ranking first in the world plastic consumption. In the late 1960s, polyethylene replaced PVC. Although PVC plastics now rank the second, its output still accounts for more than a quarter of the total plastic output.

PVC was discovered twice in the 19thcentury, once in 1835 by Henri Victor Regnault and the other in 1872 by EugenBaumann. At the beginning of the 20th century, Russian chemist Ivan Ostromislenskyand German chemist Fritz Klatte of Griesheim Elektron Company tried to use PVC forbusiness, but the difficulty was how to process this hard and brittle material.

In 1926, Waldo Semon ofB.F. Goodrich Company in the United States synthesized PVC and applied for apatent in the United States. Waldo Semon and B.F. Goodrich Company developed amethod of plasticizing PVC by adding various additives in 1926 to made pvc moreflexible and easy to process, it quickly gained wide application in business.

However, in the mid-1970s, people realized that the residual monomervinyl chloride (VCM) in PVC resin and products is a substance that could resultin cancer, which would undoubtedly affect the development of PVC. But, it havesuccessfully reduced the residual VCM through automobile and other means, sothat the VCM content in PVC resin is less than 10ppm, meeting the requirementsof sanitary grade resin, and expanding the application scope of PVC. It caneven make the VCM content in the resin less than 5ppm, and the residual VCMafter processing is very little. It is basically harmless to human and can beused as food and drug packaging and children's toys.
