TopSorb desiccant after adsorption

Most desiccant products on the current market, the CaCl2 powders inside sachets turns into entire liquid when the adsorption reaches 60%~80%. This state of being liquid lasts several days or even longer (depending on the temperature & humidity conditions) , then it slowly turns into gel.
It is a high-risk period when the absorbent remains in liquid. When the desiccant sachets are squeezed or pressed during transport or operation, the joint of sealing part has a risk to be cracked and damaged. As a result, the leakage occurs from the inside liquid,and then the customers’ goods is polluted by the leakage.
TopSorb developed unique formula of absorbents, which is quite different from the other desiccant suppliers, not matter in physical appearance, or in adsorption performance.

First, it has stronger adsorption capacity over 250%~300%.

Second, fantastically, in the whole process of absorbing,the absorbent remains in solid form , no single minute turn into liquid form, from the beginning, to the full working conditions, until being saturated,

It entirely prevents the risk of liquid leakage.

2. Inspeciton of container wood floor.if possible,do not use containers with wood floor humidity over 20%,it would increase the risk of damp.

Desiccant plays an effective role only in a closed enviroment.If the container door is not shut tightly, or there is damage on the container or the air-vents inside are not sealed,desiccant will never be able to absorp up the mositure that continually enteres from outside.
