Veriflex 551

Copolymeric elastomer for wellbore cement compositions

Chemistry Type: Butadiene and acrylonitrile copolymer

Function(s): Cement Additives

Veriflex 551 reinforcing aid for wellbore cementing enables the formulation of lower density cements with improved compression and flexural strength.

Previously sold as Pliolite CM 35.

Key Advantages

  • Improves compressive and flexural strength (Young's modulus)
  • Lowers cement density - ideal for lightweight slurries
  • Extremely temperature stable at bottomhole circulating temperature (BHCT) up to 260 °C (500 °F)
  • High chemical resistance to well contaminates
  • Readily dispersible polymer powders
  • Recyclable
