PVC material information
PVC, the full name of Polyvinylchloride, the main component is polyvinyl chloride, and other ingredients to enhance its heat resistance, toughness, ductility and so on. The uppermost layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the lowermost layer is a back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. Its global use ranks second among various synthetic materials. According to statistics, in 1995 alone, PVC production in Europe was about 5 million tons, and its consumption was 5.3 million tons. In Germany, the production and consumption of PVC is an average of 1.4 million tons. PVC is being produced and applied worldwide at a rate of 4%. The growth rate of PVC in Southeast Asia is particularly significant, thanks to the urgent need for infrastructure construction in Southeast Asian countries. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material.
Pvc was first discovered in 1835 by the famous French scientist (Henri Victor Regnault). Then in 1872 another scientist in Germany (Eugen Baumann) discovered this new material. At the time, the pvc material was a white solid, which was extremely fragile and had no practical application. In the early 20th century, a group of chemists such as Ivan Ostromislensky and Fritz Klatte tried to change the fragility of pvc, making it a commercial product but ended in failure.
It was not until 1926 that 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 materials. The basis for commercialization of products. In 1931, Germany began to produce pvc with the emulsion method. In 1941, the United States began to produce pvc by the floating method, and thus the 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 With the continuous development of technology, the current pvc production synthesis has been replaced by bulk synthesis, which makes it more efficient and costs are greatly reduced.
