Lushan® MP series maleated polypropylene are produced by grafting maleic anhydride, acrylic acid and epoxy polar group onto polypropylene with special high technology, and provide polarity and reactivity which give high adhesion levels on various substrates such as inorganic fillers, fibers, metals, EVOH, PET, aluminium foils, Nylon, etc. The polar functionality in these materials facilitates printability, paintability and receptivity to adhesives in the case of extruded and moulded products. They can be used as coupling agents for fillers and reinforcement in PP compounds，adhesive promoters and compatibilizers for PP and Nylon or other polar polymer witch also act as wetting and dispersing aids for colors and pigments.
