The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin cross section. PE has excellent resistance to most domestic and industrial chemicals. With the diversification of drainage types in modern buildings, floor drainage systems have also changed in various forms, especially in bathrooms, balconies and kitchens where water is frequently used. Now there are more and more drainage design requirements, and it is often necessary to connect pipes of different materials. For example, it is common to connect pipes of PVC and PE.
