Study of Modification of R-PP Foamability by Blending with PDMS

Abstract:

The effect of PDMS on foamability of R-PP was investigated using a single screw extrusion foaming system, with supercritical carbon dioxide as the blowing agent. Experimental results indicate that the addition of a small amount of PDMS will improve expansion ratio of R-PP foamed samples. Furthermore, compared with pure R-PP, cell-population density of foamed samples obtained from R-PP/PP-g-MAH/PDMS blends was obviously higher than that of pure R-PP foams.The experimental results show that blending with PDMS is beneficial for improving foaming performance of R-PP.
