water - based fast hydration guar gum powder , non toxic guar gum polymer

Quick Detail:

Carboxymethyl guar gum is an anionic carboxymethyl hydroxypropyl guar modified from guar gum.

Description:

1. Viscosity build over time is dependent on pH, shear rates, and temperature. This polymer is a self-hydrating polymer; therefore, no external buffer systems are required to control viscosity development.

This polymer also hydrates well at 40° F and 80° F, therefore performing well in cold environments. It is

sensitive to salts, but will easily develop adequate viscosity to be functional. This polymer is alcohol

tolerant and will viscosify a 50% solution MeOH.

2. Carboxymethyl hydroxypropyl guar gum is applied as a fracturing fluid in the recovery of oil and gas.

It is a self-hydrating polymer, so no external buffer system is required to help viscosity development.

Applications:

1. Put Carboxymethyl guar gum into the water with rapid agitation, adding at the point of greatest agitation. Viscosity will develop without adjusting solution Ph value.

2. As a stimulation fluid, this polymer exhibits good thermal stability and can be crosslinked with a number

of transitional metal ions, including borates. Typically, if crosslinking the carboxyl group, an aluminum

complexing agent is suggested. This polymer exhibits excellent carrying capacity to support sand or

other proppants.

Specifications:

Competitive Advantage:

1.With its excellent carrying capacity, carboxymethyl hydroxypropyl guar gum can support sand or other

prop-pants, and it is alcohol tolerant while it is kind of sensitive to salts.

As a stimulation fluid, carboxymethyl hydroxypropyl guar gum has good thermal stability and can be

cross-linked with a number of transitional metal ions.
