Elastomer for Oil Well Cement

Product Description :

G404 elastomer for oil well cement, using the crack resistance and toughening properties of composite fibers to improve the toughness of cement stone.

Performance Characteristics :

  • Non-toxic, odorless.
  • Common dosage is 1.5% ~ 4.0% (BWOC).
  • There is no adverse effect on the thickening time, rheology and free water of the cement slurry, and the compressive strength is obviously improved.
  • Applicable to all types of cement slurry.
  • Available for dry mixing, but not available for mixing with water.

Technical indicators :
