High-density polyethylene (HDPE) is a thermoplastic polymer manufactured from the monomer ethylene. It is the popular plastic holding enormous versatile polymer that suits a wide range of applications. It is a cost-effective thermoplastic with a linear structure with no or low degree of branching. The plastic is manufactured in at a temperature of 70-300 degrees under a pressure bar of 10-80 bar.
The product is prepared from the ethylene by a catalytic process. The absence of branching results to more close structure with higher density. HDPE is a durable, versatile, abrasion, low cost, and chemically resistant plastic material. It is available in sheets, and rods that require greater stiffness and strength then LDPE (low-density polyethylene). It is easy to fabricate by using welding equipment and is an excellent choice for fabrication.
HDPE is available in several colors including natural black, red, yellow, green, blue, and natural shades.
24 in x 48 in – 48 in x 96 in
Thickness: 0.0312 in – 0.250 in
0.250 in – 14 in
48 in x 96 in – 60 in x 120 in

Note: Length, width, diameter, thickness can vary by brand, manufacture and grade.
UV stabilized grade- It performs well in water, UV exposures, and other harsh elements. Therefore, it is a popular choice for marine construction, outdoor cabinetry and playgrounds.
HDPE for O & P – Its hard and stiff than polypro and hence used for applications which seeks for durability, and support.
Meets regulatory requirements – For direct and indirect food contact, the product is resistant to cleaning chemicals, hot water, and won’t absorb any bacteria or odors.
