Silica gel is the most used desiccant beads in our daily life. it is
always a granular, vitreous, porous form of silica made synthetically
from sodium silicate. Despite its name, silica gel is a solid. It is a
naturally occurring mineral that is purified and processed into either
granular or beaded form. As a desiccant, it has an average pore size of
2.4 nanometers and has a strong affinity for water molecules.a

Desiccant silica gel packets:
Silica gel packets are those tiny little packets that seem to be inside
all types of packaging. When silica gel packs are
placed inside shoe boxes, they help to prevent leather shoes from
becoming moist and covered with mildew or ruinous mold. When silica gel
desiccant is used in food packaging, food items stay fresher longer and
are not prone to early spoilage.Silica gel packets in all types of packaging is because it is very
harmless.The gel contains numerous tiny pores that are designed to
absorb and hold moisture.
Silica gel indicator beads:
Blue silica gel indicator
It is the cobalt in the cobalt chloride indicator that is responsible
for the toxic labellingand disposal restrictions on this product.
It is still though considered as non-hazardous for transportation
purposes.Changing from blue (dry) to pink in a near-exhausetd state, it
is supplied in 2 - 5 mm beadedor 3 - 6 mm granular forms.
Orange indicating silica gel
Using an organic indicator this silica gel offers a very strong orange
(dry) to dark green (near exhausted)
colour change. Mostly used in a low dust beaded form with granular
versions also available.
Orange to Colourless.
Silicone gel desiccant advantage & uses
has high adsorptive capability, possess the feature of non-
deformable, non-deliquescent, non-toxic, and smell-less in saturate
state, moreover, in conveniently use and pack, generally utilized in
the moisture-resistant desiccant such as electron, hardware, textile,
food, medicine, container and etc.
