According to the size of its pore size, it is divided into: large pores, coarse pores, B type, and fine pores.
Due to the different pore structures, their adsorption properties have their own characteristics. Coarse-pored silicone has a higher adsorption capacity when the relative humidity is high; fine-pored silicone has a higher adsorption capacity than coarse-pored silicone when the relative humidity is low, and B-type silicone has a pore structure between coarse and fine pores. Between silicone, its adsorption capacity is also between coarse and fine pores. Macroporous silicone is generally used as catalyst carrier, matting agent, toothpaste abrasive, etc.
