1. Essentially different


PPR Pipe Fittings are also called three-type polypropylene pipes. They are made of random copolymer polypropylene and extruded into pipes and injection-molded into pipe fittings. PVC is actually a vinyl polymer and its material is an amorphous material.


2. Different performance


PPR is the late 1980s, using gas-phase copolymerization process to make about 5% of PE randomly and uniformly polymerized in the PP molecular chain (random copolymerization) to become a new generation of pipeline materials, it has good impact resistance and long-term creep performance .


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 occasions in contact with aromatic hydrocarbons and chlorinated hydrocarbons.



3. Different production materials


Due to different production materials, the color of PPR pipe and PVC pipe products are different. PPR pipes made of polypropylene have a bright appearance and better ductility. Depending on the color masterbatch added, other color pipes can be produced; PVC pipes are mostly milky white and have a shiny surface, but no cross-section, so 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.


PPR pipe has the characteristics of light weight, corrosion resistance, no scaling and long service life. It is one of the most widely used water supply pipelines in home improvement projects. The interface of the PPR tube uses hot-melt technology, and the tubes are completely fused together, so once the installation and pressure test passes, the reliability is high.


The raw materials used in the production of PPR pipes and PVC pipes are different. PPR pipes are made of copolymer polypropylene materials, while PVC pipes are made of polyvinyl chloride materials. The different production materials result in different performances. .


Due to material reasons, PVC pipes and PPR pipes have low hygiene and safety. Yajie PPR pipes are generally used as water supply pipes in home improvement, which can be used for hot and cold water pipes, and PVC pipes are often used for drain pipes. Cold water pipes.
