PP (Polypropylene) granules is a nontoxic, odorless, tasteless, creamy, high crystalline polymer with a density of only 0.90 -- 0.91g/cm3, one of the lightest plastics available. It is particularly stable with water, with a water absorption rate of 0.01%. PP has the advantages of excellent comprehensive properties, good chemical stability, good shape processing performance and relatively low cost.It can adapt to a wider range of application requirements through modifying, copolymerization,grafting,blending, reinforced filling, transparency filling.
