With the improvement of technology, color is no longer the standard to distinguish ppr tubes. The quality of the pipe can't solve the problem just by looking at it. If touched, coarse particles are likely to be mixed with other impurities.
2、? Smell? Is there any smell? The main material of ppr pipe is polypropylene. Good pipes have no smell, and bad ones have a strange smell, probably mixed with polyethylene, not polypropylene.
