What Is MPP Foam Sheet Microcellular Polypropylene foam, referred to as MPP, MPP Foam Sheet refers specifically to polypropylene porous foam material with a cell size of less than 100 microns (more strictly defined as a cell size of less than 10 microns, with a cell size of The hole density is greater than 10 to the 9th power/cm3). Due to the existence of a large number of micron-sized cells inside the material, MPP has excellent shock absorption, cushioning, heat insulation and sound absorption properties, and can be widely used in packaging, vehicles, bags, sports equipment and other fields. It is the traditional EVA, PU, The best substitute for PS foam material, EPE and EPP. Performance and Application Supercritical carbon dioxide technology (supercritical carbon dioxide) is used to prepare MPP. Carbon dioxide gas is introduced into the polypropylene material matrix under high temperature and high pressure, and its nucleation and foaming are induced to form a microcellular foam material containing a large number of micron-scale cells. The foaming process is clean and pollution-free, and the foamed products are hygienic and environmentally friendly. The PP material is not cross-linked during the foaming process, so it can be recycled and reused. Suzhou Shincell New Material Co., Ltd. is a professional Foam Sheet Manufacturers.
