High density polyethylene panels are a popular choice for many applications due to their durability and versatility. They are made from a type of plastic called high density polyethylene (HDPE), which is known for its high strength-to-density ratio.
One of the key properties of HDPE is its high impact resistance, which means it can withstand heavy loads and harsh environments without cracking or breaking. This makes it an ideal material for use in outdoor applications.
HDPE panels are also resistant to corrosion, which is a major advantage in coastal or industrial areas where saltwater and chemicals can damage other materials. They are also easy to clean and maintain, making them a practical choice for many industries.
HDPE panels can be used in a variety of applications, including wall cladding, roofing, and flooring.
Product Information

Properties and Features
High density polyethylene panels are made from a durable material that can withstand various environmental conditions. The panels have a density of 29.4 – 28.7 g/cm^3, according to ASTM D792.

The panels are also resistant to water, with a water absorption rate of less than 0.01% after 24 hours, as per ASTM D570. This makes them ideal for use in wet or humid environments.
In terms of mechanical properties, the panels have a flexural modulus of 400,000 psi, as per ASTM D790. This indicates their ability to resist deformation under load. They also have a hardness of D69, measured using the Shore D scale.
Here are some key properties of high density polyethylene panels:
The panels' thermal properties are also noteworthy, with a coefficient of linear thermal expansion of 6.1 – 7.2 (x 10^-5 in./in./°F), as per ASTM D256. This indicates their ability to expand and contract with temperature changes.
