Under normal circumstances, PVC water pipes appear white. If different materials are added for functional requirements, PVC water pipes will appear in corresponding colors, but white is still the main color. The difference is that the color of PPR water pipes is not mainly white, and most of the time there are transparent particles, which can be presented in different colors by adding different colors of masterbatch. In addition, the colors of PPR water pipes used as hot and cold water pipes are not the same. Usually, there are blue marking lines on the cold water pipes and red marking lines on the hot water pipes.
