Bentonite Clay

Bentonite Clay is used as the absorbent of clay desiccant, which is widely used in machinery parts, precise instruments, electric and metal products and military-industries products etc. It is known as a green product due to its absolute safety and 100% environmental friendliness. It is non-toxic and non-rusty, containing no any additive and calcium chloride. It can be regenerated for repeated use at low temperature without deterioration.

Top-Sorb takes pride in its bentonite mine in Inner Mongolia. Comparing with other similar products, our bentonite clay has strong advantages as follows:

a. adsorption capacity reaches 25~27% at 25℃,RH=80%

b. water loss less than 0.7% (170℃)

c. montmorillonite content higher than 95%

Top-Sorb supply bulk clay in particle size: 0.5~1.5mm, 1~3mm, 1~4mm, 0.5~4mm etc.
