Suspension polyvinyl chloride PVC resin body [palyvinyl chloride (bulk polymerization)] China has the production of injection pvc pipe supply, Sichuan Yibin Tianyuan, 内蒙古海吉 two companies, the method of product transparency and insulation than other methods . Solution polymerization of PVC resin used for surface coating on. At low temperature 20 ~ 30 ℃ or below 0 ℃ suspension, emulsion polymerization or bulk polymerization, both said low temperature. High molecular weight low temperature polymerization of PVC, high crystallinity, structural regularity is good, high glass transition temperature, heat resistance, solvent resistance is good. But difficult to process than ordinary PVC, lower impact strength, used for fiber and specialty plastics. The resulting emulsion PVC production called Emulsion PVC (Emulsion poly-merixation). It is a paste resin, high molecular weight, smaller particles. Emulsion PVC Model RH-xy, where R- emulsion method; H- paste resin; x- absolute viscosity resin ene solution; y- paste viscosity. x points 1,2,3 type, a type of absolute viscosity of 2.01-2.4mPa · s, type 2 absolute viscosity of 1.81 ~ 2.00mPa · s pvc injection pipe price, type 3 absolute viscosity of 1.60 ~ 1.80mPa · s. y points Ⅰ, Ⅱ, Ⅲ number, number Ⅰ paste viscosity of not more than 3,000mPa · s, Ⅱ No. paste viscosity of 3000 ~ 7000mPa · s, Ⅲ number paste viscosity of 7,000 ~ 10 pvc injection tube, 000mPa · s. In 1912, the German Fritz Klatte synthesized PVC pvc injection pipe manufacturers, and applied for a patent in Germany, but before the patent expired not been able to develop the right products. In 1926, the American BF Goodrich Company's Waldo Semon PVC synthesized and applied for a patent in the United States. Waldo Semon and the BF Goodrich Company in 1926 to develop the use of adding various additives plasticized PVC method, making the material more pliable and easier to process a wide range of commercial applications soon injection pvc pipe prices, pvc injection tube, sea Widex Widex provided by Qingdao Rubber Material Co., Ltd. Widex Qingdao Rubber Material Co., Ltd. (www.haihuidaxiangsu.com) strong, credible, in Qingdao, Shandong industrial products industry has accumulated a large number of loyal customers.
