  Specifications
  Dynapac PAC/CMC for oil drilling industry.
  Hgh-purity, high-efficiency slurrying agent.
  Rsistant to salt, base and moisture.

  Properties:
  1, high degree of substitution, good substituent distribution .
  2, high transparency, viscosity, could be use from fresh water to the saturation of any mud.
  3, Resistant to heat, salt and bad environment
  4, stabilize soft soil structure, prevent collapse of wall of a well .
  5, improve mud-making volume, reduce fluid loss .
