High Purity Sodium Carboxymethylcellulose (CMC)

ANTISOL™ Polyanionic Cellulose (PAC) Polymers are high purity (>98%) sodium carboxymethylcellulose (CMC) products. ANTISOL™ polymers serve as the industry standard to modify rheology and filtration behavior of water based drilling fluids in well drilling, Horizontal Directional Drilling (HDD) and geothermal boreholes. The unique set of features of ANTISOL™ polymers simplifies drilling mud composition and limits the need for multiple additives.
