BlackGold Improved Guar Gum LH-203

 

Product: Carboxymethyl Hydroxypropyl Guar Gum

Abbreviation: CMHPG

CAS Number: 68130-15-4

 

Description:

LH-203 is a double-modified guar gum from carboxymethyl hydroxypropyl ether, specially designed for petroleum industry as additives for aqueous and water/methanol-based fracturing fluids. It can achieve high viscosity without any buffer systems. It can release 90% viscosity immediately within 3 minutes.

 

Applications:

LH-203 can be used in high temperature deep wells hydraulic fracturing. These applications utilize its properties to increase viscosity, reduce fluid loss and decrease fluid friction. It hydrates faster, contains less insoluble material, and has improved temperature stability, wide chemical compatibility and gel breaking easily and thoroughly.
