Both theoretical and practical experience shows that the MRS and safety factors of PVC are much higher than that of PE, that is, the intensity and safety of long-term use are higher than PE. Thus the same 75mm pipes with PVC raw material than the PE material production of pipe wall thickness is much, this is due to the PE material at room temperature and long term strength than high PVC, only through increased wall thickness to increase the intensity. If we take the same wall thickness, PE pipe is not up to the requirements of the use of strength. If we take the same diameter, PVC pipe diameter is PE pipe high water. If the quantity of water to achieve the same need, PE pipe larger diameter, the engineering costs increased significantly. It shows that the high strength and rigidity of the PVC material is economical and practical for the use of the water supply pipeline.
Polyvinyl chloride (PVC) is a polar molecule, than monomers vinyl chloride (PE) and some small molecule is relatively stable, therefore less susceptible to environmental effects. However, it is now the emergence of crosslinked vinyl chloride and other polymers, will be improved in this regard.
PE pipe from R & D put to the market, to replace the UPVC pipe, seizes the market, become the most pipe selection of choice, this is the fundamental reason; first from the material properties of the PE pipe of speaking, than other pipes to many quality; in addition, often the test of the market, the consumer market also from experience to the excellent quality of PE pipe. Below from several aspects to analysis, PE pipe compared to UPVC pipe performance and application market, so as to judge the future prospects for the development of PE pipe.
Plastic products are most likely to cause people to misunderstand is the so-called "toxic and non-toxic" problem. Polyvinyl chloride may be the deepest of these misunderstandings. In science, there are no toxic and non - toxic classification of plastic products, but ordinary plastic and food hygiene grade plastic problems. In fact, the vast majority of plastics are non-toxic, they can make food packaging, medical supplies, and even for the production of some of the bones and organs of the human body.
