CMG LH-301

400-6362-678

Product: Carboxymethyl Guar Gum
Abbreviation: CMG
CAS Number: 39346-76-4

Description:

LH-301 is modified carboxymethyl guar gum. It is a self-hydrating polymer. The viscosity is depend on ph, shear rates and temperature. No external buffer systems are required to control viscosity releasing.

Applications:

LH-301 is used as a fracturing fluid in the recovery of oil and gas. It exhibits very good hydration in cold water (40° F) as well as warmer water (80° F or higher) and is somewhat sensitive to alcohols and monovalent salts. As a stimulation fluid, it exhibits good thermal stability and can be crosslinked with transitional metal ions, as well as borates. When crosslinking the carboxyl group, an aluminum complexing agent is recommended. It exhibits excellent carrying capacity to support sand or other proppants to be placed in the fractured area.
