Silica gel is a porous material of different particle sizes which is properly dehydrated from silicic acid gel.It is a good desiccant, adsorbent and catalyst carrier.
Silica gel is a granular, glass, porous form of silica from the synthesis of sodium silicate.
Silicone is hard and laborious;Stronger than ordinary household gelatins and agar-like AGAR.
It is a naturally occurring mineral refined and processed into any granular or beaded form.
As a desiccant, it has an average pore diameter of 2.4 nanometers and a strong affinity for water molecules.Food grade silica gel is non-toxic, tasteless, insoluble in water and any solvent, is a green product with high activity.The product has the good softness, satisfies the different demand.
Silica gel raw materials are divided into: ordinary industrial silica gel, food grade silica gel, platinum grade silica gel.Ordinary silica gel is used to make industrial accessories, miscellaneous parts, etc., food-grade silica gel to make household accessories, etc., platinum silica gel to make high-performance silica gel products, platinum is a vulcanizing agent to enhance the performance of various products of a catalyst.
However, no matter ordinary or food grade can make us feel at ease to use, silica gel colorless tasteless, add a variety of color glue mix into a variety of bright colors mistakenly let us think of it as toxic color!
