WebProduction of High Density Polyethylene via Slurry Process; via Solution Process; and via Gas Phase Process. In the gas phase process, ethene and hydrogen are combined, and the resulting mixture is passed over a Philips catalyst in a fixed bed reactor to finally achieve polymerisation reaction and produce High Density Polyethylene grains. 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.
