    what is silica gel and why do i find little packets of it in everything i buy?

    moisture is always present in the air which affects the characteristics of almost all substances.
    the moisture in the air penetrates through the toughest of the packaging walls and passes through all layers of your protective shields.
    moisture penetrates through a closed room, box, plastic bags, metal containers & through glass bottles.

    every year, thousands of rupees worth of products are damaged due to moisture; metal components corrode, electronic equipment catches fungus, cardboard boxes get wet, and products get moldy and become unfit for usage. pharmaceutical products, ayurvedic & nutracuticals are also affected heavily. the best solutions is here finest quality of silica gel.

    standard white silica gel is referred to as being non-indicating. as it adsorbs moisture it remains physically unchanged. non-indicating silica gel is both cheap and effective, available loose in bulk packs or packed in sachets.

    they are dmf free and cobalt free into best permit able non-woven cloth so as to absorb 67.82% of moisture available in sizes of in 0.5,1,2,3,5,10,25, 50,100,250, 500grams and 1kg and 2kg.

    little packets of silica gel are found in all sorts of products because silica gel is a desiccant -- it adsorbs and holds water vapor. in leather products and foods like pepperoni, the lack of moisture can limit the growth of mold and reduce spoilage. in electronics it prevents condensation, which might damage the electronics. if a bottle of vitamins contained any moisture vapor and were cooled rapidly, the condensing moisture would ruin the pills. you will find little silica gel packets in anything that would be affected by excess moisture or condensation.

    silica gel is nearly harmless, which is why you find it in food products. silica, or silicon dioxide (sio2), is the same material found in quartz. the gel form contains millions of tiny pores that can adsorb and hold moisture. silica gel is essentially porous sand.
    silica gel can adsorb about 40 percent of its weight in moisture and can take the relative humidity in a closed container down to about 40 percent. once saturated, you can drive the moisture off and reuse silica gel by heating it above 300 degrees f (150 c).
