Silica-gel is a high-activity sorbing material, the outcome of chemical reaction of sodium silicate and sulfuric acid, ageing and sour bathing process. Silica-gel is an amorphous substance. Its molecular formula is mSiO2.nH2O.It conforms to the China Chemical Standard HG/T2765-2005,and it is the only desiccant approved by FDA which can touch food and medicine directly.
After absorbed moisture,white silica gel won’t have color changed (but if been put in colored air condition for long time, and inpoured by colored air molecules,it will be dyed).The blue and orange silica gel desiccant have indicator function,after moisture absorbing,the blue silica gel desiccant will turn into red,and orange silica gel will turn into green.
Blue Silica Gel including 3‰-5‰ cobalt chloride, Orange Silica Gel including 0.9‰methyl violet (Eco-friendly)
Granularity qualified rate
Moisture absorption rate
1. Moisture absorption rate over 30%
2. No physical forms changed after moisture absorbing, no toxic,no harm,no pollution.
3. Good heat stability, strong mechanical strength
4. Widely used in shoes,hats,leathers,handbags,food,medicine,metals,toys,bamboo and wood,instruments,electronics,etc.
Features of Composite Paper:
1. Printing clear, easily identifiable the warnings
2. General air permeability and firmness
3. Competitive price
Simple self-test method for effectiveness:
1. Tear off the silica gel desiccant package,hold some silica gel material in hand tightly, if the silica gel become hot,that means the desiccant still in work.
2. For silica gel desiccant with blue and orange indicator,the silica gel desiccant is useless when indicator color changed.
3. Take a cup of cold water, rip the desiccant package and pour the silica gel into water, if the silica gel beads blown to pieces,and make sounds,that means the desiccants are still in work.
4. Take a silica gel desiccant pouch, weigh and mark, put it indoor,after 5-10 days, weigh again, if its weight increased, that means the desiccant still work.
5. For precise moisture absorption performance of the desiccant, lab test equipments are necessary.
