In-house rubber compound mixing for the oil and gas industry

GP Rubber makes 40+ different rubber compounds in-house in its facility in Haltom City, TX (DFW area). Watch a video about our facility. Batch sizes range from 40-120 lbs. and enable us to exactly meet your specifications in temperature, chemical and abrasion resistance. In-house compounding also allows us to take control of lead-time rather than relying on an outside compounder.

Common compounds used include these that are well-proven in downhole environments:

  • Aflas
  • Silicones
  • Fluroelastomers
  • Nitriles
  • Carboxylated Nitriles
  • H.S.N./HNBR (Hydrogenated Nitrile)
