 PP-R pipe, how to identify performance 

 "See" the appearance of 

 Color, good color and soft PP-R pipe uniform, non-variegated. (PP-R pipes are mainly lime green, yellow several consumers tend to believe that white is the best, in fact, color is not to judge good or bad quality standards, in fact, PP-R pipe is good or bad with the PP-R pipe color no plastic particles of white, transparent color (there are other colors has been added to lust mother) mainly adding the masterbatch color can be produced, the masterbatch is not broken down will not change the PP-R quality, single mains, what color does not matter, as provided for by the state, PP-R pipe to have a good close-light performance, point gray or opaque performance will be better, but this advantage is only in the next tube The decoration of the pipes are all Buried in the installation and pipe shaft, so there was never gray is better than other colors ". PP-R pipe is completely opaque, pseudo-PP-R pipe slight translucent or semi-permeable the light. white products are generally only pure PP-R materials, such as addition of the products produced of recycled materials, waste, angle material, its color is not soft nor uniform, add other colors of masterbatch processing recycled materials, waste angle is expected, will not affect the product color. This is why the focus on the quality of many manufacturers of home improvement retail-based products are mainly white); products inside and outside surfaces should be smooth, does not allow any air bubbles, apparent depression. trench and impurities and other defects. 

 "Touch" texture 

 100% good PP-R pipe PP-R materials (any material to add) pure texture, smooth surface, soft touch, the pseudo-PP-R pipe, smooth feel, In general, the coarse particles are likely to blending of the impurities; 

 "Smell" the smell of 

 PP-R pipe material is polypropylene, a good pipe does not smell, poor smell is likely to be blending a polyethylene instead of polypropylene; 

 "Pinch" hardness 

 PP-R pipe has considerable hardness, casually can pinch the deformation of the tube, is certainly not of PP-R pipe;
