PE board, PE rods, PP board, PP rods, PVC board, PVC rods, CPVC board, CPVC bar What performance characteristics?
PVC pipe: In fact, is a plastic pipe, the interface is generally bonded with glue, UPVC pipe frost resistance and heat resistance are not good, it is difficult to use as hot water pipe, because its strength can not be applied to the water pipe bearing Pressure requirements, so cold water pipes are rarely used. In most cases, PVC pipe for wire and sewage pipes. In addition, in recent years, the technology sector found that PVC can become more soft chemical additives phthalide, the human body kidney, liver is very big, can lead to cancer, kidney damage, destruction of human function system, affecting development. So it is recommended not to buy and use, but can be used for the floor of the water Oh ~ ~
PE water supply pipe
? Water supply PE pipe is the traditional steel pipe, PVC drinking water pipe replacement products. Water pipes must withstand a certain pressure, usually to use a large molecular weight, mechanical properties of better PE resin, such as HDPE resin. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficulty in connection, and is not suitable as a material for water supply pressure pipes. However, due to its higher health indicators, LDPE, especially LLDPE resin has become a common material for the production of drinking water pipes. LDPE, LLDPE resin melt viscosity is small, good mobility, easy processing, and thus its melt index selection range is also wide, usually MI between 0.3-3g / 10min.
