New generation of high-density polyethylene

Germany has successfully developed a new generation of high-density polyethylene - DH5273, DH5973. Its structural characteristics are that the molecular chain is non-polar and homogenous, and has excellent stability against acids, alkalis, electrolytes, solvents, greases, etc., and has a high resistance to environmental stress cracking. With the blow-molding process, it is usually processed into hollow containers for medium and small household and industrial chemical reagents from several milliliters to 20 liters. Among them, DH5273 has excellent stability against strong surfactants and excellent mechanical properties, while DH5973 has better strength than previous materials at the same stress crack resistance value.
