Poly Anionic Cellulose PAC LV/HV
CAS No.: 9004-32-4
Formula: C6h7o2(Oh)2CH2coona
Product Description:
Poly Anionic Cellulose, PAC is white or yellowish powder, non-toxic and odorless.It is a cellulose derivative manufactured through chemical synthesis, available as Cream white free flowing powder. The mud fluid prepared with this product has good water loss, inhibition and high temperature resistance. Widely used as drilling mud additives in oil drilling industry, especially salt Wells and offshore oil drilling. It can be dissolved in water, has good heat stability and salt resistance, strong antimicrobial properties. Low Viscosity PAC is a kind of high quality, low molecular weight and low viscosity cellulose polymers. High Viscosity PAC is a kind of high quality, high molecular weight, high viscosity cellulose polymers.
