In the United States sales HDPE1/3 for blowing purposes. These range from bleach, oil, detergent, milk and bottles of distilled water to a large refrigerator, car fuel tanks and cylindrical tanks. Blow molding grade properties, melt strength, ES-CR and toughness, and used in sheet and thermoforming applications level similar to similar grades can be used.
