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…
WebHigh Density Polyethylene (HDPE) is a type of plastic that is commonly used in the manufacturing of various products, including packaging materials, toys, and construction materials. While HDPE is known for its durability and strength, it has also been criticized for its negative impact on the environment.
