Material Properties
High-density polyethylene (HDPE) is a thermoplastic polymer produced from the monomer ethylene. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber. HDPE is commonly recycled, and has the number "2" as its resin identification code.
HDPE is known for its high strength-to-density ratio. The density of HDPE can range from 930 to 970 kg/m3. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength than LDPE. The difference in strength exceeds the difference in density, giving HDPE a higher specific strength. It is also harder and more opaque and can withstand somewhat higher temperatures (120 °C/248 °F for short periods). High-density polyethylene, unlike polypropylene, cannot withstand normally required autoclaving conditions. The lack of branching is ensured by an appropriate choice of catalyst (e.g., Ziegler–Natta catalysts) and reaction conditions.
HDPE is resistant to many different solvents.
INTERESTING FACTS
Why is HDPE so Popular?
Products made of high density polyethylene are long-lasting and easy to maintain. Food stored in HDPE containers does not get contaminated by the polymer, making it quite safe for humans. Some important attributes of this polymer are highlighted in this subsection.
Moldability
HDPE retains its rigid structure until its melting point is reached.
Once in the melt state, this polymer can be easily molded into any desired shape.
This property makes it an ideal choice in the production of food containers, water bottles, and plastic lumber.
Resistance to Corrosion
This polymer is resistant to mould and rotting, making it an ideal choice for making underground water pipes.
Since HDPE can be sterilized via boiling, it is safe to use for food containing purposes.
Its resistance to many chemicals, such as mineral acids and cleaning fluids, make it easy to maintain. It is also resistant to many common solvents and acids.
Strength to Density Ratio
The density of this polymer ranges from 930 kg/m3 to 930 kg/m3.
The structure of HDPE is linear and it contains very little branching, resulting in stronger intermolecular forces.
The tensile strength of high-density polyethylene is very high – it can withstand heavier loads than most of the other types of polyethylene.
Recyclable
The resin identification code of HDPE is 2, it can be recycled easily.
Despite being non-biodegradable, it is still considered an environmentally responsible plastic.
Recycled HDPE is used in plastic furniture, automobile parts, and rubbish cans.
To summarize, high-density polyethylene owes its popularity to its low weight, high tensile strength, high impact resistance, resistance to chemicals and high temperatures, and its ability to be easily molded.
