How to buy PP-R pipe

1. “Touch”: Whether the texture is fine and the particles are even. Nowadays, PP-R pipes mainly have white, gray and green colors. Under normal circumstances, recycled plastics can't be white, so consumers tend to think that white is the . In fact, this view is one-sided. As technology updates increase, color is not the standard for identifying PP-R pipes. The quality of the pipe is not able to solve the problem. Touching it, the coarse particles are likely to be mixed with other impurities.

2. "Smell": There is no smell. The main material of the PP-R pipe is polypropylene. The good pipe has no odor, and the poor one has a strange smell. It is likely to be blended with polyethylene instead of polypropylene.

3. “Pinch”: The PP-R pipe has a considerable hardness, and it is possible to pinch the deformed pipe, which is certainly not a PP-R pipe.

4. “Pound”: Good PP-R pipe, “rebound” is good, too easy to chop is not a good PP-R pipe. However, the hardness is not equal to the elasticity. If the PP-R pipe is not broken, consumers should leave doubts. Because some unscrupulous manufacturers increase the hardness of the pipe by adding too much impurities such as calcium carbonate, such a pipe is prone to brittle cracking for a long time.

5. "burning": Ignite and burn, it is very intuitive and very useful. The PP-R pipe, which is mixed with recycled plastic and other impurities, emits black smoke and has a pungent odor. After burning, the good material will not emit black smoke or odor, and the liquid melted after burning will remain clean.
