In 1926, Waldo Semon (BF Goodrich) of the United States synthesized PVC and applied for a patent in the United States. He solved the friability of pvc by synthesizing various additives, and increased the expandability of pvc material products. The basis for commercialization of products. In 1931, Germany began to produce pvc by emulsion method. In 1941, the United States began to produce pvc by floating method, and thus pvc material related products began to be widely used in production and life applications. With the continuous development of technology, the current pvc production synthesis has been replaced by bulk synthesis, which makes it more efficient and costs are greatly reduced.
