Why doesn't the PPR tube breed bacteria and scale?
The PPR pipe material is random copolymer polypropylene, which is a low-polar saturated aliphatic hydrocarbon long-chain polymer. The product PPR pipe has a lower surface tension, so that water cannot infiltrate the pipe wall. Even at higher temperatures, water Nor can it infiltrate the surface of the pipe. The PPR material itself is extremely difficult to serve as a nutrient for bacteria, so it is difficult for bacteria to adhere to the surface of the pipeline, and it is difficult for the calcium and magnesium ions in the water to accumulate and scale on the pipe wall.
The PPR pipe material is modified polypropylene. Why is it non-toxic and tasteless?
The special material for PP-R pipes is a small amount of ethylene and propylene, which is randomly polymerized by gas phase copolymerization. It is a chemical modification, which is different from the general physical modification of adding other additives. Its long molecular chain is composed of only two elements, C and H, and does not contain any toxic elements and does not release harmful substances.
