We offer a wide variety of high density polyethylene for both injection and extrusion blow molding, in many different melt flow rates and densities from virgin prime grade, off-grade resins, reprocessed pellets, regranulates and agglomerates. HDPE that we provide can be used for different applications:
semi-transparent blow molding for film purposes
white blow molding for film purposes
red, blue or mix color injection grade
semi-transparent, blow molding
grey-black color, blow molding
mix color, film blowing or pipe extrusion
Plastic Properties of High Density Polyethylene HDPE
A linear polymer, High Density Polyethylene is prepared from ethylene by a catalytic process. The absence of branching results in a more closely packed structure with a higher density and somewhat higher chemical resistance than LDPE. HDPE is also somewhat harder and more opaque and it can withstand rather higher temperatures 120° Celsius for short periods, 110° Celsius continuously.
HDPE Quick Facts
Excellent resistance (no attack) to dilute and concentrated Acids, Alcohols and Bases.
Good resistance (minor attack) to Aldehydes, Esters, Aliphatic and Aromatic Hydrocarbons, Ketones and Mineral and Vegetable Oils.
Limited resistance (moderate attack and suitable for short term use only) to Halogenated Hydrocarbons and Oxidizing Agents.

High density polyethylene lends itself particularly well to blow molding, e.g. for bottles, cutting boards, dipping baskets, dippers, trays and containers.
