Polyanionic cellulose regular grade (PAC R or PAC HV) is a premium grade modified cellulose with high viscosity and high molecular weight which can be used as a viscosifier and fluid loss control additive in water-based drilling mud systems. PAC R can provide excellent viscosity and reduce API filtration rate for oil well drilling fluids. API 13A and OCMA grades polyanionic cellulose (pac) in oil and gas drilling can help control fluid loss and coat drilling cuttings. Polyanionic cellulose is also widely used in food industry. Food grade cellulose gum is a major thickener in bread, soft drinking and toothpaste products. Bichain is one of reliable polyanionic cellulose suppliers and manufacturers in high viscosity mud pac drilling. We supply high-quality PAC HV products like Antisol, Polypac, Drispac and Aqua pac.
Advantages:
 ►Reduces filtration rate of drilling fluids
 ►Improves and increases and drilling fluids rheology (suspension and hole cleaning)
 ►Stabilizes fluid rheology of drilling fluids with contaminants
 ►Coat and encapsulate waste solids and cuttings for drilling mud, Inhibit swelling and disintegration of water sensitive solids
 ►Improves the character and consistency of wall cake, thereby reducing the potential for stuck pipe
