Filled with environmentally friendly flame retardant masterbatch PP preferred Jinhua-liter, good resistance to climate science aging, dialysis, high openness easy to color, free of heavy metals. Spread with plastics, and anti-oxygen strong anti-aging supplement volume and other unique place, reinforced by complementary products hardness, rigidity, compression wear and reduce product shrinkage and variations due to shrinkage motivated type. Thus solving most of the problems retardant PP molding, satisfaction is not the same demand. PP flame retardant masterbatch spread good performance, suitable for use in injection molding, extrusion sheet, extruded pipe. Particle flow, and no dust, easy to operate and feed, overcome by mixing powder flame caused by uneven quality uncertain issues; the use of safe reliable, background and who hold office have a satisfactory health security . Have a high liquid concentration, good spread, simplify production processes, cost-effective high strengths, instead of powdered flame retardants absolutely. PP is not the same melt index is not the same, the best addition ratio of the flame retardant is also slightly different, the optimum addition ratio exceeds the greater the amount of flame-retardant effect actually worse, it is proposed that the appropriate use melting means 10 above homo PP material.
