It is estimated that the domestic market demand for green PE pipe fittings may be in more than 12% per year rate continues to grow, especially as China continues to accelerate the pace of modern city building, strengthening water resource treatment, water supply and drainage systems, building heating systems PPR pipe production line machinery, water supply, sewage, gas, heating pipes, large diameter underground pipe, and so will be very broad application prospects PPR pipe production line, plastic pipe production in China in 2010 will reach 4.5 million tons PPR pipe production line Which is better? To reach 6 million tons in 2015, when China will become the largest country in the world production of plastic pipe. Thus, pipe production companies need to seize the opportunity to continuously open up new application areas, strengthen brand promotion. HDPE is a high crystallinity, non-polar thermoplastic resin. Original state of HDPE milky white appearance in thin cross-section was a certain degree of translucent. PE has excellent resistance to most of the characteristics of living and industrial chemicals. Certain types of chemicals will undergo chemical corrosion, such as corrosive oxidizer (nitric acid), aromatics (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is not hygroscopic and has good water vapor resistance, can be used for packaging purposes. HDPE has good electrical properties PPR pipe production line, especially high insulation dielectric strength, making it suitable for wire and cable. Medium to high molecular weight grades with excellent impact resistance, at ordinary temperature even at -40F temperatures are so low. The unique characteristics of the various grades of HDPE is an appropriate combination of four basic variables: density, molecular weight, molecular weight distribution and additives. Different catalysts are used to produce customized special properties of the polymer. These variables combine to produce different uses of HDPE grade; to achieve the best balance between performance.
