Carboxymethyl Cellulose (CMC) is widely used in food-making, detergent, papermaking, oil-drilling, textile, dyeing, ceramics, construction, paint, welding, battery, medicine, tobacco, toothpaste, cosmetics, etc. We can supply CMC of different grades .
Sodium Carboxymethyl Cellulose Drilling Fluids CMC
CMC can be used as fluid loss reducer or viscosifier in drilling fluids. The function of CMC is to reduce the fluid loss as much as possible through forming low permeability, flexible, thin and compact filtration cake on borehole wall. Used as thickening agent, suspension agent and plugging agent.
CMC can reduce water loss, and increase viscosity in drilling fluid, cementing fluid and fracturing fluid. They play the roles of protecting the wall of well, taking drilling trifles, protecting drilling bit,preventing mud loss and increasing drilling rate.

Grade of Carboxy Methyl Cellulose-CMC:
Oil Drilling Grade CMC: It can increase viscosity and reduce water loss in drilling fluid, cementing fluid and fracturing fluid. It also plays the role of protecting the wall of well, taking drilling trifles, protecting drilling bit, preventing mud loss and increasing drilling rate.
It's used for ceramic embryo, glazing pulp and colored glaze in ceramic industry.
Detergent Grade CMC
Paint Grade CMC
Textile and Dyeing Grade CMC:
it is used in textile and dyeing industry as sizing agent and texture finishing agent. It is a good stabilizer, thickener, emulsifier and suspending agent in textile dyeing, and easy to desizing.
Tech Grade CMC
Food Grade CMC
1. 25kg/bag,The solid product can be packed in inner plastic bags, and further in polypropylene woven bags.
2. This product is hygroscopic, so it is should be sealed and stored in a dry and cool place below 35°C.
3. The solid product should be prevented from scattering on the ground because the hygroscopic powder can cause slipperiness.
