Typical Properties
HDPE (high density polyethylene) is available as sheet or rod stock for applications that require greater strength and stiffness than LDPE.

HDPE with an embossed surface is widely used as a cutting board material in restaurants and food processing plants.

HDPE is easy to weld using thermoplastic welding equipment and is an excellent choice for fabricated water tanks and chemical tanks that must be assembled by thermoplastic welding.
