The relationship between PPR tube color and quality
The PPR tubes we usually see are mostly white, green and gray. Some people say that the white tube is non-toxic and the gray tube is toxic. Some people think that the gray tube is a recycled tube, and they don’t want to use it. The color of the table depends on its inherent quality. The so-called white color, green color or gray color is based on the company's relevant regulations and the special needs of users.
Adding white, green or gray color masterbatch to each of them to produce white, green, and gray pipes, Whether it is toxic or non-toxic depends on whether the content of lead, cadmium, tin, mercury, and vinyl chloride monomer in the pipe meets.

For the appearance, the manufacturer must increase the number of colorants and deepen the color. , The appearance may be gray or black, but it cannot be concluded that all gray or black plastic pipes are recycled pipes. Strictly speaking, no color will have any effect on PPR pipe material.
