HDPE Packaging Solutions (High Density Polyethylene)

HDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m . The standard method to test plastic density is ISO 1183 part 2 (gradient columns), alternatively ISO 1183 part 1 (MVS2PRO density analyzer). 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 (38 MPa versus 21 MPa) than LDPE. The diff… WebHDPE. Delivering a balance of toughness, stiffness, environmental stress crack resistance (ESCR), and processability, high-density polyethylene (HDPE) resins are well-suited for a range of rigid applications like IBCs and storage tanks; crates and pallets; pails and lids; automotive components; bottles and caps; toys and water sports equipment.
