Product description:
Blue discoloration of silicone is a high-grade adsorption dryer with high value-added,high-tech,indicating adsorbent which is made by deep processing with the basic material of highly active adsorption pore silica gel.Using the pore silica gel(aperture2-3nm,surface area beyond 600m2/g ) as a carrier,make cobalt chloride(Cocl2) combined to the surface of internal voids through a certain process.
It's glassy particles,we can divided it into spherical and lump according to the particle shape.It act as silica gel in anti-moisture and adsorption,and the original color changes from blue to purple until light red with the increasing of adsorption,not only indicating humidity but also directly shows whether it's anti-moisture or not.

Application:
It's mainly used in moisture absorption and anti-rust of instruments,equipments in confined condition.It's also used in conjunction with ordinary silica gel desiccant to instruct moisture level of desiccant and judge the relative humidity of the environment.It's now widely used in sophisticated instruments,leather,shoes,clothing,food,medicine and home appliances and so on.
Recycling:
After moisture and the color changed,we can recovery it's original color by heating it at 100℃-120℃ and then we can reuse it.
Specifications:
1-3mm,2-4mm,3-5mm,granular or spherical.
Packaging:
Packaging,specifications,text,special signs can designed according to customers.Usually it can be any packing form 1g-25kg/bag,with Non woven paper,PE,PP,Tyvek,cotton or others.
