silica gel is a kind of highly activated adsorption material. It is white and translucent glass-like. Silica gel is a form of silica dioxide(SiO2),nonpoisonous and odorless with chemical stability.Except for alkali and hydrofluoric acid,it does not react with any other
substance.According to the different pore diameters of silica gels.they are categorized into large pore silica gel,macro-pored silica,Silica Gel Type B and Fine-pored silica gel.The capacities of absorption vary duc to their different pore structures.Macro-
Pored has a high absorptive capacity at a high relative humidity,fine-pored has a higher absorptive capacity than macro-pored at a low relative humidity.The absorptive capcity of Type B is between Macro-pored and Fine-cored.Silica gel mainly uses Type A and Type B as its raw material.It absorbs water vapor,odors and other condensed vapors in a container via a static absorption.It is widely used in electronics,food,pharmaceutical apparatus,machinery,textile,handicrafts,toys and transportation,Package of different materials and different sizes are available to satisfy customer'needs.
