ANTISOL™ FL polyanionic cellulose (PAC) polymers are available in a variety of high and low viscosities, and are used to modify flow and filtration properties in water-based drilling fluids. These high-purity (98%) carboxymethylcellulose polymers perform essential functions, such as the following: dispersion of clay particles that occurs as a result of the polymer adsorption on the particles' surface; protection of the clay particles against the detrimental effects of electrolytes; retaining "free" water in the drilling fluid that could penetrate into the formation; preventing the swelling of shale formations and the dispersion of the shale in the drilling fluid.

ChemPoint EMEA is an approved supplier of ANTISOL™ FL polyanionic cellulose (PAC) polymers in water well drilling applications, providing dedicated marketing, sales, order fulfillment, and technical support for customers located Western Europe.
