The HIPS micro foaming sheet equipment adopts the new environment-friendly supercritical carbon dioxide foaming technology to innovate the traditional non foaming products, and greatly reduce the production cost under the condition that the use characteristics of raw materials (anti-static, ultraviolet resistant, flame retardant, anti-corrosion, low temperature resistant, high temperature resistant, anti-skid) are unchanged. The product grade can not only meet the needs of industrial grade, but also meet the needs of medical grade and food grade. It is mainly used for: refrigerators and household appliances, advertising and printing industry, breeding equipment, stationery, children's toys, car interior decoration, building materials, bags, etc.
