Silica Gel is a granular, porous form of silica made synthetically from sodium silicate. Despite the name, silica gel is a solid. Silica gel is the highest capacity adsorbent available today. It comprises of tiny inter-connecting pores, it attracts and holds moisture by adsorption and capillary condensation. Silica gel is chemically inert, non-toxic, non-flammable and safe to use to protect foods, medicines, sensitive materials and much more. Even when saturated with adsorbed moisture, silica gel looks and feels dry to the touch. Silica gel is most commonly encountered in everyday life as beads packed in a semi - permeableplastic. In this form, it is used as a dessicant to control local humidity in order to avoid spoilage of some goods. Silica gel is a desiccant, or drying agent and should not be confused with silicon gel Trade Name : Silica Gel Chemical Family : Sodium Silicate Chemical Name : Synthetic Silica Gel Chemical Formula : SiO2+H2O+CoCl2 Properties Silica gel's high surface area (around 800 mÂ²/g) allows it to absorb water readily, making it useful as a desiccant (drying agent). Once saturated with water, the gel can be regenerated by heating to 120Â Â°C (250Â Â°F) for two hours. Some types of silica gel will "pop" when exposed to enough water.

We manufacture both indicating and non indicating type of Silica Gel. It is available in different sizes suitable for use with a wide range of applications. White silica gel is referred to as being non-indicating as it remains physically unchanged after adsorbing moisture. Non-indicating silica gel is both cheap and effective, available loose in bulk packs or packed in sachets of non woven paper or cloth or as desired by the customer whereas self indicating silica gel is relatively expensive since it contains a color indicator namely Cobalt Chloride.
We manufacture Silica Gel as per the Indian Standard Specification as well as also for specific requirements of our esteemed clients.
