The color difference of PPR water pipes: The color of PPR water pipes with good color is soft and uniform, without variegation. PPR pipes are mainly white, gray, green and yellow. Consumers often think that white is the best. In fact, color is not the standard for judging the quality. In fact, the quality of PPR water pipes has nothing to do with the color of PPR water pipes. Plastic particles are mainly white and transparent (there are also other colors that have been added with color masterbatch). As long as the color masterbatch is added, any color can be produced, and the color masterbatch will not be decomposed and will not change the quality of PPR. Color doesn't matter either. According to national regulations, PPR water pipes must have good light-tight performance. In this regard, gray or other light-tight performance will be better, but such advantages only exist in open pipe installations and pipe wells. All water pipes for home improvement are dark. Therefore, there is no saying that gray is better than other colors. The PPR tube is completely opaque, and the pseudo-PPR tube is slightly transparent or semi-transparent. Generally, white products can only be produced with pure PPR raw materials. For example, the color of products produced by adding recycled materials, waste materials, and corner materials is not soft and uneven, while other color products processed with masterbatches are added with recycled materials, waste materials, corner materials, etc. It will not affect the color of the product. This is why many manufacturers who focus on quality and focus on home improvement retail mainly use white products. The inner and outer surfaces of high-quality PPR products should be smooth and flat, and defects such as air bubbles, obvious depressions, grooves, and impurities are not allowed.
