the full name of Polyvinylchlorid, the main ingredient

PVC, the full name of Polyvinylchlorid, the main ingredient for the polyvinyl chloride, in addition to other ingredients to enhance its heat resistance, toughness, ductility and so on. The top layer of this surface film is a paint, the middle of the main component is polyvinyl chloride, the bottom is the back coating adhesive. It is the world's favorite, quite popular and also widely used in a synthetic material. PVC can be divided into soft PVC and hard PVC. Which accounted for about 2/3 of the hard PVC market, soft PVC accounted for 1/3 Soft PVC is generally used for the floor, ceiling and leather surface, but because the soft PVC contains softeners (which is the difference between soft PVC and hard PVC), easy to become brittle, easy to save, so its use has been limited. Hard PVC does not contain softener, so flexible, easy to shape, not brittle, non-toxic and pollution-free, long storage time, so it has great development and application value. Development of PVC Profilescustomized pvc decorative profile/pvc profiles for fence During the Ninth Five-Year Plan period, China gained an average annual rate of 8% growth in the economy. In the recommendations of the Tenth Five-Year Plan, it clearly pointed out that further strengthening the infrastructure construction and implementing the urbanization strategy provided a broad development for the national construction industry Space. PVC pipe industry status quowhite rigid pvc profile extruding plastic furniture profile As one of the products of scientific and technological development, PVC pipe in the daily life of touch. In Europe, the growth rate of plastic pipes from 1980 to 1990 was 8%, and in 2001 the output reached 3.5 million tons, of which PVC pipes accounted for 60%. The United States in 1985 plastic pipe production of 1.6 million tons in 1999, the output of about 3.6 million tons, of which, PVC pipe accounted for 78%. China's first UPVV flared pipe was born in Shenyang in 1983 in Shenyang Plastic Factory (now the predecessor of Shenyang Jiuli). Since then, mainland China has the production capacity of PVC and drain. The late 1990s is the high-speed development period of PVC pipe in mainland China. During the period of some annual production capacity of more than 50,000 tons of factories have been put into operation, more than 10,000 tons of production scale PVC pipe factory of more than 30. The annual production capacity of plastic pipes in 2013 is 2 million tons.
