1. PVC PVC (PolyVinylChloride) generally has 7 grades (SG1-SG7) according to the hardness and performance of the material, and the density is about 1.4 g / cm ^ 3. Below SG4 is generally a soft product, and a large amount of plasticizer needs to be added during molding. It is mainly used to make artificial leather, wire and cable insulation, and seals. SG5 and above are hard products, mainly used
What is the difference between PVC and CPVC? 1. Material characteristics: PVC is polymerized by vinyl chloride monomer (VCM). PVC material has the characteristics of non-toxic, anti-aging and acid and alkali resistance, so it is very suitable for use in chemical pipelines. The mixture of PVC raw materials with a certain amount of solid additives (no plasticizers) is called rigid polyvinyl ch
UPVC / CPVC pipe material instructions 1. Material characteristics: PVC is polymerized by vinyl chloride monomer (VCM). PVC material has the characteristics of non-toxic, anti-aging and acid and alkali resistance, so it is very suitable for use in chemical pipelines.

PVC or poly vinyl is a kind of thermoplastic resin in synthetic polymer resins, and UPVC pipeline special adhesive is a single-component solvent-based adhesive. PVC-U (Hard Polyethylene Fluoride) pipes are used for water supply pipes (non-potable water), drainage pipes, rainwater pipes, etc. PVC-C pipes (recorded poly vinyl) are used for hot and cold water pipes, fire water pipe systems and ind
1. Plasticization difference: UPVC is hard PVC, and a certain amount of modification aid is added on the basis of PVC resin powder to produce a modified material. Therefore, the main difference between UPVC and 100 PVC and soft PVC is that no plasticizer is added, calcium powder is more, and the material has high mechanical strength. 2. Chlorine content difference: CPVC is chlorinated polyvinyl
The cold knowledge is coming: precautions for the use of pe water pipes Due to its unique advantages, pe water supply pipe is widely used in construction water supply, construction drainage and other fields. In order to ensure the ideal use effect of the pipe and avoid other failures during use, we need to pay attention to the following points when using : 1. Welding: When hot-melting, the
1. Urban water supply: PE pipe head has comprehensive advantages such as safety, sanitation and convenient construction, and has become an ideal pipe material for urban water supply. 2. Natural gas and gas transportation: PVC has become the best choice for medium and low-pressure natural gas transportation pipelines due to a series of advantages such as reliable PE connection, stable performanc
Cold knowledge: What you must know about PE water supply pipe PE water supply pipes are commonly used in municipal engineering. It is often necessary to find suitable manufacturers to purchase pipes that meet engineering requirements. When inquiring manufacturers, they often need to provide specific parameter requirements. Many people do not understand the common knowledge of PE water supply pi
