POLY-BORE ®

POLY-BORE® is a 100% dry, free-flowing granular polymer that is water-soluble and easy to mix. POLY-BORE® is a partially hydrolyzed polyacrylamide polymer (EPSP) with a very high molecular weight. When mixed with fresh water, a small amount of POLY-BORE® provides a clear, viscous, solids-free stabilizing liquid for use in auger wells, horizontal directional drilling, trenching […]

POLY-BORE® is a 100% dry, free-flowing granular polymer that is water-soluble and easy to mix. POLY-BORE® is a partially hydrolyzed polyacrylamide polymer (EPSP) with a very high molecular weight. When mixed with fresh water, a small amount of POLY-BORE® provides a clear, viscous, solids-free stabilizing liquid for use in auger wells, horizontal directional drilling, trenching and reverse circulation (RC) drilling.

Recommended treatment

Construction applications

  • Add 3 to 10 pounds (1.4 to 4.5 kilograms) of POLY-BORE® dry polymer slowly to the mixing hopper with 1,000 gallons (3.8 m³) of fresh water. (See general instructions below).
  • Reverse circulation drilling
  • Add 0.5 to 1 lb (0.2 to 0.5 kg) of POLY-BORE dry polymer slowly through the mixing hopper with 100 gallons (0.38 m³) of fresh water. (See general instructions below).

General instructions

Continue mixing for a further 15-20 minutes to allow the POLY-BORE® to hydrate.

  • If POLY-BORE® is added directly to a tank with paddle-type mixers, make sure the freshwater level is above the paddles. Add POLY-BORE® slowly to the vortex created by the paddle movement.
  • Measure the funnel viscosity of the polymer paste and adjust to required specifications.

Notes :

  • The make-up water used to mix POLY-BORE® must have the following qualities:
    • total chloride less than 1500 ppm (mg/L)
    • total hardness below 150 ppm as for calcium
    • total chlorine less than 100 ppm
    • Water pH between 8.5 and 9.5
  • Reduce total hardness of make-up water by adding 1 to 2 pounds (0.45 to 0.9 kg) of soda ash (sodium carbonate) per 1,000 gallons (3.8 m³) of make-up water. (Do not add in excess, as over-treatment can cause adverse effects and reduce drilling fluid performance).
  • POLY-BORE® can be chemically decomposed with ordinary liquid bleach (5% sodium hypochlorite). Use one gallon of bleach for every 100 gallons (10 litres/m³) of POLY-BORE® liquid. Do not use perfumed bleach or solid calcium hypochlorite.

Packaging

POLY-BORE® is available in 14 lb (6.35 kg) plastic containers.
