In 1912, the German Fritz Klatte synthesized PVC and applied for a patent in Germany, but was unable to develop a suitable product before the patent expired.
In 1926, Waldo Semon of B.F. Goodrich Company synthesized PVC and applied for a patent in the United States. Waldo Semon and B.F. Goodrich Company developed a method of plasticizing PVC by adding various additives in 1926, making it a more flexible and easier to process material and quickly gaining widespread commercial application.
PVC is polyvinyl chloride, amorphous structure of white powder, poor stability to light and heat, no fixed melting point. PVC is a kind of thermoplastic, thermoplastic molding is easy, the main thermoplastic including: polyethylene (PE),polypropylene (PP), polyvinyl chloride (PVC),Nylon (Nylon), polyurethane (PU), etc.
The biggest characteristic of PVC is: transparent, waterproof, light weight. Also has good processing performance, low manufacturing cost, corrosion resistance, good insulation and so on.
PVC can be divided into soft PVC and hard PVC. Soft PVC is generally used for floor, ceiling and leather surface, but because soft PVC contains softener (this is also the difference between soft PVC and hard PVC), easy to become brittle, not easy to preserve, so its range of use is limited. Hard PVC does not contain softener, so it has good flexibility, easy molding, not easy to crisp, non-toxic and pollution-free, long preservation time, so it has great development and application value. The essence of PVC is a kind of vacuum plastic film, used for all kinds of panel surface packaging, so it is also known as decorative film, adhesive film.
There are many styles of PVC bags, exquisite and beautiful appearance, transparent products, can improve the product packaging grade, widely used in gift shops, cosmetics stores, shopping malls and supermarkets product packaging. Many handbags are made of PVC.
Raincoat, hot water bag, waterproof mobile phone bag, cosmetic storage bag, jewelry sealing bag and file bag are all made of PVC.
