PVC products are widely used due to its good performance, as well as its economy and environmental protection.

The fact that PVC products do have the right properties makes them the material of choice in many areas and applications of our modern society. PVC-U pipe strength is very high, its minimum required strength (MRS) reached 25MPa, while the polyolefin pipe relatively high grade PE100 MRS value is only 10MPa, PVC-U pipe is 2.5 times its.

Another reason that PVC products are selected for competition with other materials is that it is the most cost-effective. Since most of the plastic (resin) is made of petroleum, the price of the resin depends on the price of petroleum. In particular, the plastic variety that consumes a large amount of ethylene in production (producing 1 kg of polyethylene consumes 1 kg of ethylene and produces 1 kg of polychlor Ethylene needs 0.43 kg of ethylene), and as the price of oil continues to rise, its resin prices have remained high for quite some time. PVC, which uses coal as its raw material, is less affected by high oil prices and remains at a relatively low price, thus enhancing its competitiveness.

Another reason why PVC products last, because it is an eco-friendly product. It is well known that the production of caustic soda is the basis of the chemical industry. For our country alone, 9 million tons of caustic soda are produced each year. A large amount of chlorine gas is produced during the manufacture of caustic soda by electrolysis of salt. Chlorine gas is a poisonous, harmful and irritating gas. If it is inadvertently leaked into the atmosphere, air, the environment and the surrounding organisms can cause serious Therefore, it is necessary to digest the chlorine gas generated, and the production of polyvinyl chloride resin is the best way to consume a large amount of chlorine. Therefore, from the perspective of the country's macroeconomic policies and environmental protection, PVC is an environmentally-friendly product that the country is making efforts to develop and protect.
