Changes and trends—efficiency of physical blowing agents in polyurethane foam materials

HIGHLIGHTS

• who: Haozhen Wang et al. from the School of Energy and Environmental Engineering, University of Science and Technology Beijing, Beijing, China have published the paper: Changes and Trendsu2014Efficiency of Physical Blowing Agents in Polyurethane Foam Materials, in the Journal: Materials 2023, 3186 of /2023/
• what: In this study, taking the part of the foam volume increase during foaming process as the core, the effective mass of the PBA during the foaming process was calculated by combining the limited measurable physical parameters with relevant formulas.
• how: The dimensions of the pressure sensor used in . . .
