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.

What Is Microcellular Foam Molding Technology The use of foaming technology in plastic processing can reduce the weight of the product, but the traditional foaming process uses petroleum gas (such as butane, pentane) as the foaming agent. , The demand for safe and stable new foaming agents continues to expand. Under normal conditions, the amount of carbon dioxide or nitrogen dissolved in the molten resin is very small, which is not enough for foaming. Technical advantages - Greatly improve product dimensional accuracy and shorten product development cycle; - Significantly reduce product residual stress, reduce and improve product warpage deformation, and improve dimensional accuracy; - Eliminate the surface sink marks, no sink marks on the surface of the product; - Effectively shorten the molding cycle of thin-walled products and improve production efficiency; - Effectively save raw materials, reduce product quality and save raw materials; - Reduce clamping force requirements and save manufacturing costs; - The foaming agent is low cost, environmentally friendly and suitable for all application fields; - Improve product dimensional accuracy and stability; - The fluidity of the mixed sol is enhanced by 20%-40%, the viscosity is low, and the filling effect is obvious; - The microporous structure effectively improves the internal stress distribution; - The supercritical gas equipment is simple in process, low in cost, and environmentally friendly; - Zero emission of pollutants in the manufacturing process, and the products do not contain chemical residues. Economic advantage - Gain the means to reduce manufacturing costs in the long term - Get an easy way to improve product quality - Access to strategic development opportunities We are a professional manufacturer of microporous foam boards.
