1. High adsorption capacity: it can effectively absorb more than 200% of its own weight moisture in packaging test, and more than 400% in naked sample test. 2 all-weather: it can work as usual under the temperature and humidity conditions of -10 ℃-80℃ and RH% 10-99. When the temperature is higher than 40℃, the adsorption capacity of the silica gel desiccant decreases. When the temperature is lower than 0℃, the desiccant almost loses its adsorption capacity. 3 high efficiency and long duration: super fast hygroscopic speed can make the environmental humidity quickly reduce to the ideal humidity, super high hygroscopic capacity (the maximum hygroscopic capacity reaches more than 300% of the dead weight, depending on the variety). To ensure the durability of hygroscopic capacity, at room temperature often wet hygroscopic 60-90 days. 4. More economical and economical: more than 10 times as effective as silica gel desiccant (depending on the variety), greatly reducing cost and resource consumption. 5. Environment friendly: all the raw materials are non-toxic, tasteless and pollution-free food grade raw materials. This product does not contain dimethyl fumarate and cobalt chloride. It is 100% biodegradable and tested by international authoritative institutions. It fully complies with EU RoHS, REACH and other standards
