Good PP-R pipe, "resilience" Well, of course, not good is easy smash PP-R pipe. But hardness is strong does not mean good elasticity, some manufacturers by adding too much calcium carbonate and other impurities to improve the hardness, how are smashing is not broken, with a long easy to crack. Sixth, the "burning" smoke odor. Raw materials are mixed with recycled plastic and other impurities in PP-R pipe will be black smoke, pungent odor. And after the good material does not burn black smoke, no smell, after combustion, tpu, melt the liquid is still very clean.
