SILICA GEL
SILICA GEL WHITE CRYSTAL BEEDS.MAINLY USED IN SHOE INDUSTRY AND OTHER INDUSTRIES.
WEIGHT- 2 GRAM SACHETS
PACKET- 1 KG
COLOUR- CRYSTAL WHITE
DESCRIPTION AND PROPERTIES
Silica gel is an amorphous and porous form of silicon dioxide (silica), consisting of an irregular tridimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores. The voids may contain water or some other liquids, or may be filled by gas or vacuum. In the last case, the material is properly called silica xerogel.

Silica xerogel with an average pore size of 2.4 nanometers has a strong affinity for water molecules and is widely used as a desiccant. It is hard and translucent, but considerably softer than massive silica glass or quartz; and remains hard when saturated with water.
Silica xerogel is usually commercialized as coarse granules or beads, a few millimeters in diameter. Some grains may contain small amounts of indicator substance that changes color when they have absorbed some water. Small paper envelopes containing silica xerogel pellets, usually with a "do not eat" warning, are often included in dry food packages to absorb any humidity that might cause spoilage of the food.
'Wet' silica gel, as may be freshly prepared from alkalisilicate solutions, may vary in consistency from a soft transparent gel, similar to gelatin or agar, to a hard solid, namely a water-logged xerogel. It is sometimes used in laboratory processes, for example to suppress convection in liquids or prevent settling of suspended particles.
- OPT Silica gel desiccant adsorbs moisture from the air in enclosed spaces.
- Give a longer life by absorbing the moisture and eliminate fungus, mould.
- The moisture absorber is ideal for closed spaces of shoe cabinets, camera lenses, bags, wardrobes or wherever stagnant air is a problem.
- Protect your valuables from mould, mildew, moth,foul smell,rusting, spoilage and fungus.
- To use, simply place this sachet in a ziplock pouch or air tight container along with the product to protect the product from moisture damage.
- You can replace the product when the silica gel beads change their colour (orange turns into green, blue turns into pink, white doesn’t change.
