HDPE LH523台聚 LH523 is a high density polyethylene (HDPE)especially developed for injection molding. In addition, it can beapplied to powder coating after grinding.
High melt index of UNITHENE LH523 makes it exhibit excellentprocessability. Also, UNITHENE LH523 possesses superb impactstrength and resistance to stress crack owing to its lowerdensity.
LH523 can be easily pigmented to any color by either dry blendingor melt blending of the pigment into the resin. The products ofLH523 can be easily printed after flame, chemical or electronicsurface treatment.
