The difference between PPR and PVC pipes is as follows:
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% 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. Different colors: PPR pipes and PVC pipes have different colors. The PPR pipe made of polypropylene material has a bright appearance and better toughness. According to the addition of color master batch, other color pipes can be produced; PVC pipes are mostly milky white, with glossy surface, but no cross section, and the material is relatively fragile.
4. Different production costs: Due to the material and wall thickness, the production costs and prices of PPR pipes and PVC pipes are also different. Generally speaking, the price of PPR pipes is relatively high.
