PAC
Introduction
PAC is an ether derivatives of natural cellulose after chemical modification.it is a kind of water-soluble glues, both in cold and hot water with the features of bonding, thickening, emulsification, dispersion, suspension, stability, film, and so on.
Applied range
A kind of water-soluble glues (hydrosol) with good performance
Function
As drilling mud agent, our PAC has a good resistance to salt,high temperature and filtration, it can be used for the preparation of the various kinds of drilling fluid and for the maintenance of drilling to improve fluid performance.
As oil fracturing , it improves the suspended-sand performance ,reduces filtration and frictional resistance and makes pressure transfer effectively
