PDC drill bits. Polycrystalline diamond materials, for use in polycrystalline diamond compact (PDC) bits, are one of the most important material advances for oil drilling tools in recent years. Fixed-head bits rotate as one piece and contain no separately moving parts. When fixed-head bits use PDC cutters, they are commonly called PDC bits.
The chemical name for Nitrile rubber is Butadiene Acrylonitrile. However, most commonly it is referred to as NBR or Buna-N. NBR is probably the most common solenoid valve seal material and it is considered the standard material for neutral fluids by many.NBR is also the standard material for O-rings.PDM solenoid valve seals are well suited for use with hot water due to EPDM's excellent resistance to heat. The maximum service temperature of EPDM is approximately 120 degrees Celsius. EPDM is unsuitable for use with most oils and fuels.
