Sanyou PVC industrial pipes have high mechanical strength and good corrosion resistance. It can be used to make waste gas discharge and detoxification towers, gas and liquid delivery pipes for industries such as chemical and textile, and can also replace other corrosion-resistant materials to manufacture storage tanks, centrifugal pumps, ventilation fans, and joints. When the amount of plasticizer added reaches 30% to 40%, soft polyvinyl chloride is produced, which has high elongation, soft products, and good corrosion resistance and electrical insulation. It is often made into thin films for industrial packaging, agricultural seedling cultivation, daily raincoats, tablecloths, etc. It can also be used to make acid and alkali resistant hoses, cable sheaths, insulation layers, etc.
