产品描述
DMDE-6620 NT 7 Bimodal High Density Polyethylene Resin is produced by UNIPOL™ II process technology. This resin is a high stiffness resin with superior top-load performance in conjunction with excellent environmental stress crack resistance and excellent gas barrier properties. DMDE-6620 NT 7 is specifically designed for use in multiple types of blow molding processes, producing containers up to 20 gallons in size, which require superior top-load combined with excellent environmental stress crack resistance and gas barrier properties. This product offers excellent processability with low plate out properties. This product is especially well suited for containers used to package household industrial chemicals (e.g. detergents, and fabric softeners), toiletries and cosmetics (e.g. shampoos, creams, lotions, etc.), health, pharmaceutical, and food products.
