SILICA GEL
» Silica Gel (White)
Silica gel (White) will adsorb moisture in exactly the same way as silica gel (Blue), but they will Not indicate when they are becoming saturated by changing their colour. It will remain white when they are becoming saturated.
This is useful in fillers, catalysts supports, adsorbent, dehydrating agent and as the buffing media in toothpaste.

Packing: 25kg in bag, 25, 40, 50 kg in cardboard barrel or iron or in H.D.P.E. drum; 12.5kg in iron drum; 500kg in container bag
» Silica Gel (Blue)
In this type all the gel particles are impregnated with an indicator. When free from moisture the crystals of silica gel are blue.
As they are put to use, the crystals can take up moisture, it gradually turns pink and gives a ready indication that done its work and need replacement or regeneration.

» Silica Gel (Orange)
Our orange silica gel is not impregnated with cobalt chloride, it is the latest product that can replace the blue silica gel indicator. The composite dyeing agent without pollution to the environment has been successfully adopted during the manufacturing process of the orange silica gel. In this way, it has prevent the Cobalt chloride from polluting the environment from the very beginning.

There are two types with the orange silica gel . One is Orange Dark green Type, it discolors from orange into dark green during the process of moisture adsorption; another is Orange - Colourless Type, it discolors from orange into light green when adsorbing moisture. Both the orange silica gel have much more adsorption capacity than that of the blue silical gel.
Particle size : We offer various particle size ranges as below:

In mesh size : 1/2, 3/4, 3/6, 3/8, 5/8,9/16, 16/30, 30/60 mesh

In mm. : 10-20, 8-10, 6-10, 4-10, 6-8, 4-8, 3-8, 4 -6, 3-5, 2-5, 1.5-2, 1-2, 1-1.5 mm.

Packing: 25kg in bag, 25, 40, 50 kg in cardboard barrel or iron or in H.D.P.E. drum; 12.5kg in iron drum; 500kg in container bag
» Silica Gel Sachets
Silica gel sachets or bags are simply flexible 'containers ' of silica gel. The sachet material has to be robust and capable of withstanding normal handling whilst importantly being able to breathe. This means that water molecules can pass through the material and be adsorbed by the silica gel. Standard sachet materials are tea-bag paper, fabric or cotton.

We produce a range of standard size silica gel sachets using (white) or (orange/green, orange/colorless or blue) silica gel. In the latter case, the colors of the gel are visible through the sachet paper or fabric. Silica gel sachets are often useful in test situations, to confirm the suitability of the sachet size chosen.
Application of Silica Gel sachets

Small silica gel sachets (0.5 to 10 gram) can prevent moisture damage to electrical goods and electronic components, scientific and optical instruments, communication equipment, metallic parts, leather goods, tools and many other small to medium sized items in use, store or transit.
Sachets size:

We offer various sachet ranges in heat-sealed non-woven fabric and in cloth fabric as below:

Grams: 0.5, 1, 2, 3, 5, 10, 15, 20, 25, 40, 50, 100, 250, 500 gram. & 1, 2, 2.5, 4, 5 kg.
