China's plastic pipe industry, has been the rapid development of pvc plastic profiles manufacturers in the expanding pipeline of products from plastic pipe market, has become a ubiquitous product has been widely recognized as an important industry. Plastic pipe products are all aspects of attention, especially in the construction sector, the water sector, public works engineers and technicians in the field are very concerned about, understand, study plastic products. "Fifteen" period, the rapid growth of the plastic pipe industry, and promote the technological progress of the industry. Many enterprises attach great importance to the international forefront of technology, attention to the development and introduction of new technologies and new product pvc plastic profiles, and the introduction of advanced processing equipment at the same pvc plastic profile products, continue to strengthen research and development of new products. Some large companies have their own advanced level of research and development centers, with a strong technical strength. Domestic plastic pipe industry already has 300 number of inventions, new patented technology, and some proprietary products leading position in the International Office. The gap between the technical level with the developed countries is gradually narrowing, has evolved from a simple import substitution into an international export products. Variety, structure, new materials, new technologies, new processes and patents more and more plastic pipe, a variety of different types of plastic pipe is playing to their strengths in different applications. Rigid PVC is one of the most widely used plastic materials. PVC material is a non-crystalline materials. PVC material in actual use, often by adding stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives. PVC material is not easily flammable, high strength, resistance to climate variability and excellent geometric stability. PVC oxidant, reductant and acid has a very strong resistance. However, it can be concentrated oxidizing acids such as sulfuric acid, concentrated nitric acid corrosion and does not apply to contact with aromatic hydrocarbons, chlorinated hydrocarbons occasions. pvc plastic profile processing _ sea Widex (certified) _pvc plastic profiles provided by Qingdao Rubber Material Co., Widex.
