Low density polyethylene is LDPE and similarly HDPE for high-density Polyethylene. Lastly, UHMW stands for Ultra High Molecular Weight polyethylene. Although Polyethylene is a thermoplastic material that can be challenging to bond these structural acrylics form excellent bonds. Structural Acrylics 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.
