Properties of High Density Polyethylene (HDPE) Plastic
High-density polyethylene. HPDE is made from
hydrocarbons found in petroleum. HDPE is flexible yet more rigid, 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: 248°F for short periods, 230°F continuously. HDPE has a good
impact strength, a good resistance to stress crack, 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
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

HDPE products are available in many forms such as sheet, rod and tubing for
Excellent for all food related products, FDA,
NSF, and USDA approved for direct contact.
Very Good chemical resistance and high rigidity make it a excellent choice
for containers and tanks.
Some other uses include pipe fittings, buckets, barrels and drums.
Excellent impact resistance, light weight, very low moisture
absorption, & high tensile strength.
