The PPR pipes sold on the market mainly have several colors such as green, white, gray, and black. The raw material of the ppr pipe is transparent particles without color, and different colors are only added with different color masterbatches, so the color of the PPR water pipe and Quality is not necessarily related, but it is generally recommended to buy white PPR tubes, because very few profit-oriented manufacturers will use recycled materials to produce PPR tubes, and add color masterbatch to cover up the defects caused by impure raw materials.
In addition, there are more cases where white PPR fails to pass the light-proof inspection, while gray and green do not have these problems. In addition, affected by living habits, white PPR pipes are mostly used in the north, while gray PPR pipes are mostly used in the south.
