The widespread application of PVC products is due to its excellent performance, as well as its economic and environmental friendliness.
The excellent performance of PVC products has made them a material of choice in many fields and applications in modern society. The strength of PVC-U pipes is very high, with a minimum required strength (MRS) of 25MPa, while the higher grade PE100 in polyolefin pipes has a MRS value of only 10MPa, which is 2.5 times that of PVC-U pipes.

Another reason why PVC products are chosen in competition with other materials is because they are the most cost-effective. Most plastics (resins) are made from petroleum as the raw material, so the price of resins depends on the price of petroleum, especially for plastic varieties that consume more ethylene in production (producing 1 kilogram of polyethylene requires 1 kilogram of ethylene, while producing 1 kilogram of polyvinyl chloride requires 0.43 kilograms of ethylene). With the continuous increase of petroleum prices, the resin price has also remained high for a considerable period of time. PVC, which uses coal as its raw material, is less affected by high oil prices and continues to maintain a lower price, thus enhancing its competitiveness.
Another reason why PVC products can last for a long time is that they are environmentally friendly. As is well known, the alkali industry is the foundation of the chemical industry, and in China alone, the annual production of caustic soda is 9 million tons. The process of producing caustic soda through electrolysis of table salt produces a large amount of chlorine gas, which is a toxic, harmful, and irritating gas. If it accidentally leaks into the atmosphere, it will cause serious harm to the air, environment, and surrounding organisms. Therefore, the generated chlorine gas must be digested, and the production of polyvinyl chloride resin is the best way to consume a large amount of chlorine gas. Therefore, from the perspective of national macro policies and environmental protection, polyvinyl chloride is an environmentally friendly product that the country focuses on developing and protecting.
