From the perspective of material, PVC pipes are mainly made of polyvinyl chloride resin, and a variety of auxiliary agents need to be added in the production process to improve performance. PPR pipes, on the other hand, are made of random copolymer polypropylene, which has a pure material and stable molecular structure.

In terms of performance, each has its own advantages and disadvantages. PVC pipes have strong corrosion resistance and good tolerance for general acids and alkalis, but their temperature resistance is poor, and they can only be used to transport cold water below 45℃. They are prone to deformation and aging at high temperatures. PPR pipes, on the other hand, have excellent temperature resistance and can be used in hot water environments of 70℃ for a long time. They can withstand high temperatures of up to 95℃ instantly, and their pressure resistance is also quite prominent. They can withstand high water pressure and are non-toxic and harmless, meeting the hygiene standards for drinking water.

In terms of installation method, PVC pipes often use glue or rubber ring connection, which is relatively simple to operate and does not require high technical requirements for construction personnel, but the sealing and durability of the glue connection need to be strictly controlled. PPR pipes use hot melting connection, which requires the use of professional hot melting equipment to heat and fuse the pipes and fittings, resulting in high connection strength and good sealing, reducing the risk of water leakage, but the construction process requirements are higher. The price cost is also different.
The formula of Zhongmai PVC pipe, the inner layer of PVC pipe uses lead salt stabilizer YQ102, toughener CPE135, stearic acid 1801 and other raw materials, to provide you with a high-quality, price-stable PVC pipe.
