Web1 apr 2024 · Effect of the PPAs nature on the complex viscosity at constant frequencies. The complex viscosity of samples against time is plotted in Fig. 3, at 210 ºC.As it can be seen (in Fig. 3a), at constant angular frequency 100 s − 1, the viscosities obtained are constant for HDPE, because of measurements carried out at the linear viscoelasticity region. WebHDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m 3. The standard method to test plastic density is ISO 1183 part 2 (gradient columns), alternatively ISO 1183 part 1 …
