(CAS # 9004-32-4)


DX-PAC R is a high purity/premium, high molecular weight, water soluble anionic polymer of sodium salt of carboxymethyl ether of cellulose, tailored for use in water based fluid systems for increasing viscosity while controlling filtration at low rates.

The primary function of DX-PAC R is to improve the viscosity of the drilling fluid to the desired degree while controlling the water loss at the lowest possible rates.

By adding the product, increased apparent viscosity and yield point are obtained, subsequently better and higher drill solids transfer capacity is established.


Provides shale inhibition as a protective colloid

Improves filter cake quality and stability between the wellbore and formation
