PAC Polymer is a highly efficient poly-anionic carboxy-methyl-cellulose of high purity. It significantly increases viscosity and improves the bearing capacity of the drilling fluid. Due to its excellent water-binding properties, PAC Polymer decreases filtrate and supports the formation of a thin impervious filter crust. As protective colloid, PAC Polymer prevents the swelling of penetrated clay layers, protects against further disintegration of the clay cuttings, and opimizes deposition during fluid processing.

PAC Polymer is applied as a pseudoplastic solution in geological formations in which an intensive discharge of cuttings without generation of a colloid layer is required or requested. Clay fractions can be penetrated in a safer way and with more accuracy to the drilling. When used in combination with flushing clays, PAC Polymer should not be added until the clay swelled for a sufficient amount of time due to its clay-inhibiting effect.

Please note:

When processing PAC Polymer, no specific safety measures need to be taken. Spilled PAC powder generates a slippery layer when in contact with water and should be immediately absorbed in dry form. In case of contact with eyes or skin, simple rinsing with water is sufficient.
