PP-R pipe is generally have PPR raw material together with color masterbatch in the barrel and the mixing machine mixing blend. PP-R plastic material (PP - R English name is polypropylene random （copolymer ), is short for polypropylene random copolymer, tube also is used to refer to cold water and hot water for conveying material. Pp-r pipe good toughness, high strength, excellent processing performance, high temperature creep resistant performance is good, service life is up to several decades not aging, no corrosion!
Color masterbatch played a role in water pipes are:
1, durable reinforced plastic pipe, aging resistance, can effectively enhance the pipes buried in the ground keep a longer life expectancy.
2, in the hot water pipe products processing. Color masterbatch, can effectively improve the quality of smooth appearance, to avoid peeling off the plastic pipe material.
3, color masterbatch can quickly for coloring plastics pipe, its color has the environmental protection effect, won't produce any pollution to water quality.
