Adsorption properties, thermal stability, chemical stability, high mechanical strength. Silicone widely used around the world the main reason for its non-toxic and harmless, non-corrosive, is the only official certification by the U.S. direct access to all aspects of drugs, reagents and food. Silica gel adsorption of water can be side of the thermal desorption of water to remove silicone its water desorption heating temperature control of 120-180 degrees Celsius is suitable for blue silicone controlled at 100-120 ° C is appropriate, renewable the general control of under 2% can be put into use again.
