HDPE (HIGH DENSITY POLYETHYLENE)

Material Information

HDPE is a thermoplastic that belongs to the polyolefin group of materials. HDPE is used for the largest portion of polyethylene applications, and has much more rigidity and tensile strength than LDPE, but impact strength is slightly lower due to its stiffness. Overall, HDPE offers excellent impact resistance, is lightweight, has low moisture absorption, and has high tensile strength. It is also non-toxic, non-staining, and meets FDA and USDA certification. This makes HDPE ideal for food processing. HDPE is available in sheet, strip, rod, tube, and film.
