UNITHENE® LH523 is a water insoluble, high density polyethylene (HDPE) grade. Exhibits high melt index, good processability, superb impact strength and resistance to stress crack owing to its lower density. It can be easily pigmented to any color by either dry blending or melt blending of the pigment into the resin. The products of LH523 can be easily printed after flame, chemical or electronic surface treatment. UNITHENE® LH523 by USI is developed for injection molding and can also be applied to powder coating after grinding.
