Product Descriptions:
1, CMC is sodium salt of Carboxyl Methyl Cellulose, white or pale powder, with density of 0.5-0.7 g/cm3, no odor, can absorb the moisture in air. Soluble in water, insoluble in organic solvent, it has best viscosity performance when pH = 7, when pH > 10 or pH < 5, the viscosity will decrease obviously;
2, PAC is new type and more stable modified CMC, processed by solvent-slurry processing. Because PAC has higher DS (Degree of Substitute), like 0.85~ 1.4, and with more uniform distribution of substitute group, PAC can be used in wider industries and more complicated surroundings, and meet higher technical requirements. PAC can replace CMC in all CMC's application field, and the dosage can be only 30-60% of CMC, therefore proved better performance and economical efficiency.
3, In oil drilling, CMC and PAC is widely used in water-based drilling mud, which can effectively reduce the filtration rate of many water-based oil and gas drilling fluids, CMC and PAC can also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties
