Properties of High Density Polyethylene (HDPE) Plastic

High-density polyethylene. HPDE is made from hydrocarbons found in petroleum. HDPE is flexible yet more rigid and has a stronger intermolecular force and tensile strength than low-density polyethylene (LDPE). It is also harder and more opaque and can withstand somewhat higher temperatures. HDPE has a good impact strength and resistance to stress cracks, chemicals, and vapors. However, HDPE is a poor gas barrier. Its natural color is milky white and semi-translucent, depending on its density. Its SPI resin identification code number is 2.

Common uses milk jugs, distilled water, large vinegar bottles, grocery bags, liquid laundry and dish detergent, fabric softener, motor oil, antifreeze, bleach and lotion

High density polyethylene is excellent for blow molding, such as  for bottles, Buckets, Barrels, bottles, bags and containers.

       HDPE Resistance

        Resistance to diluted and concentrated Acids, Alcohols and Bases is  Excellent
        Resistance  to Aldehydes, Esters, Aliphatic and Aromatic Hydrocarbons, Ketones and Mineral and Vegetable Oils us Very Good
        Resistance suitable for short term use only to Halogenated Hydrocarbons and Oxidizing Agents should be Limited.

        HDPE products are available in many forms, such as sheet, rod, and tubing for fabrication:

Excellent for all  food-related products, FDA, NSF and USDA approved for direct contact.
Very Good chemical resistance and high rigidity make it an excellent choice for containers and tanks.
Some other uses include pipe fittings, buckets, barrels, and drums.
Excellent  impact resistance, lightweight, very low moisture absorption, & high tensile strength.
