Razlika između PPR i PVC cijevi je sljedeća:
1. The essence is different: PPR pipe is also called three-type polypropylene pipe. It uses random co-polymerized polypropylene to be extruded into pipes and injection molded into pipe fittings; while PVC is actually a vinyl polymer, and its material is an amorphous material.
2. Different properties: PPR is a new generation of pipeline materials in the late 1980s. The gas phase co-polymerization process is used to make about 5 percent PE randomly and uniformly polymerize (random co-polymerization) in the molecular chain of PP to become a new generation of pipeline materials. It has good impact resistance and long-term creep properties. PVC has strong resistance to oxidants, reducing agents and strong acids. It can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.
3. Različite boje: PPR cijevi i PVC cijevi imaju različite boje. PPR cijev od polipropilenskog materijala ima sjajan izgled i bolju žilavost. U skladu sa dodatkom kolor master batch-a, mogu se proizvoditi cijevi drugih boja; PVC cijevi su uglavnom mliječno bijele, sjajne površine, ali bez poprečnog presjeka, a materijal je relativno lomljiv.
4. Različiti troškovi proizvodnje: Zbog materijala i debljine zida, troškovi proizvodnje i cijene PPR cijevi i PVC cijevi su također različiti. Uopšteno govoreći, cijena PPR cijevi je relativno visoka.
