EPP Raw Material Production Line
EPP (expanded polypropylene) is an engineering plastic foam material.By combining polypropylene resin with special additives and applying heat, pressure, and CO2 in an autoclave, the material is foamed into small plastic beads. These small, closed-cell foam beads are injected into a mold,where steam's heat and pressure are used to create custom molded part sin complex shapes.
