Polyurethane is used as thermal insulation layer of refrigerator and freezer for many years. As a high performance insulation material, PU is renowned for its light weight, high compressive strength and mature industrial production technology. When foam technology continues to improve, the insulation layer is continuously reduced, which provides refrigerator an even bigger inner space. With a greener blowing agent, the product itself also becomes more environment friendly.
Pouring process mainly.
Matural industrial production technology
