In this paper, the authors study thenew generation physical foaming agent cyclopentane that is environmentally friendly and completely does not destroy the ozone layer. Study investigating andevaluating the effect of content of physical foam cyclopentane on free expansion density, reaction time of rigid polyurethane foam (R-PUF), and reaction time values(cream time, gel time, tack-free time, and rise time). The morphology and size of the closed-cell of the R-PUF samples with cyclopentane concentrations increasingfrom 0% to 20% are observed by the optical microscope image and the closed-cell size distribution chart is determined by IT3 software. In addition, the physical andmechanical properties of dimensional stability and compressive strength were analyzed to evaluate the quality of the expanded R-PUF insulation in the mold using acyclopentane physical foaming agent. Experimental procedures according to Taguchi analysis on the continuous production line are aimed at giving optimalparameters for the industrial PU panel manufacturing process. The research results provide an excellent reference value for manufacturers to further improve theperformance and quality of PU panels.
