Porous materials with a pore size less than 2nm are called microporous materials. Examples of microporous materials include; Zeolites and metal organic tissues, etc. Nitrogen gas is transformed into a supercritical fluid through high temperature and pressure, and then injected into the material barrel of the injection molding machine. After being sheared by the screw, it is mixed into the plastic. After injection molding, the foaming agent inside the plastic expands into micro pores, which are smaller and more uniform than traditional foam molding. Microporous materials have three applications; 1. In terms of laboratory; 2. Medical aspects; 3. Other aspects. There are many types of shoe sole materials, which can be pided into two categories: natural sole materials and synthetic sole materials. Natural substrates include natural leather, bamboo, wood, etc; Synthetic sole materials include rubber, plastic, rubber plastic composite materials, recycled leather, elastic cardboard, etc. The common characteristics of general sole materials should be wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to fit the foot shape, not easy to deform after molding, insulation, easy to absorb moisture, etc. Sole testing items: performance testing, hardness testing, bending testing, wear resistance, slip resistance testing, yellowing resistance testing, low temperature resistance testing, etc
