UNITHENE LH523 is a high density polyethylene (HDPE) especially developed for injection molding. In addition, it can be applied to powder coating after grinding. High melt index of UNITHENE LH523 makes it exhibit excellent processability. Also, UNITHENE LH523 possesses superb impact strength and resistance to stress crack owing to its lower density. LH523 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. |
