  • Process for producing a polyurethane foam insole
    Patent number: 11787897
    Abstract: Described herein is a method for producing a PU foam insole, including the following steps of: (1) pouring the raw materials used to form a PU foam into a mould, reacting to obtain a PU sheet, where the height of the mould cavity is from about 1.0 to about 1.6 times of the total thickness of two finished insoles; (2) splitting the PU sheet into two halves in the horizontal direction to obtain two pieces of PU insole material, where one surface of the material has open pores, and the other surface of the material has a skin; and (3) attaching a piece of fabric onto the surface having open pores of the material obtained in step (2). Also described herein is a PU foam insole produced by the method.
