Other Characteristics of HDPE
HDPE (High Density Polyethylene) is a higher density version of PE (Polyethylene). A linear polymer prepared from ethylene by a catalytic process, the difference from LDPE is the absence of branching in the chain, causing a more closely packed structure to form than in LDPE. This creates not only a higher density material, but also higher chemical resistance than its low density counterpart. It is harder, stronger heavier and more opaque than LDPE and PE. HDPE can be processed in a number of ways including: plastic molding, plastic injection molding, extrusion, film blowing and blow molding.

Chemical Resistance :

Acids – Dilute	Excellent
Acids – Concentrated	Excellent
Alcohols	Excellent
Aldehydes	Good
Bases	Excellent
Esters	Good
Ethers	Good
Hydrocarbons, Aliphatic	Good
Hydrocarbons, Aromatics	Good
Hydrocarbons, Halogenated	Limited
Ketones	Good
Oils, Minerals	Good
Oil, Vegetable	Good

HDPE for Laboratories:
LDPE has many physical properties that make it ideal for packaging. These characteristics include a good resistance to chemicals and vapor, and it tends to be stress crack-resistant and lightweight. Can be sterilized by gas, gamma irradiation and chemical disinfectant.

Other uses of HDPE:
HDPE is found in many forms such as film, blow molded bottles, and injection molding. In film form HDPE is used in snack food packaging as well as cereal box liners. In blow molded bottle form, HDPE is used for milk and non-carbonated beverage bottles. In injection molded tub form HDPE is used to produce packaging for margarine, whipped toppings, and deli foods.
