硅胶(蓝色Changable指标)

Our factory can produce various size range of silica gel blue color changable. We can supply high quality silica gel blue color indicator with various size range,the color can change to pink . According to the different pore diameters of silica gels, these products are categorized into large pore silica gel, macro-pore silica gel, B-type silica gel and fine-pore silica gel. Owing to different pore structures, absorptive performances also vary.With high relative humidity, macro-pore silica gel has a relatively high absorption capacity. Meanwhile, with low relative humidity, fine-pore silica gel has a higher absorption capacity than macro-pore silica gel.The pore structure of B-type silica gel is between micro-pore and fine-pore silica gel. Large pore silica gel is usually used as catalyst carrier, matting agent, and toothpaste abrasive. Therefore, appropriate type should be selected according to specific applications.
