What is PTFE? 
PTFE stands for PolyTetraFluoroEthylene, which is the chemical term for the polymer (CF2)n.
Polytetrafluoroethylene (PTFE) is a thermoplastic member of the fluoropolymer family of plastics and has a low coefficient of friction, excellent insulating properties. More information

PTFE is chemically inert to most substances. It also can withstand high heat applications and it is well know for its anti-stick properties.
Choosing the right seat ring material is often the most challenging decision in Ball Valve Selection. To assist our customers during this process, we are willing to offer information on customer request.

  • PTFE seats are important in valves and fluid control. If sealing surface of PTFE seat is not machined well, it will affect the valve and cause valve leakage.  
  • Max. size for PTFE ball valve seats , PTFE seals and PTFE components is 1300mm of out dimension. 

BUENO specializes in machining and fabricating as molding polytetrafluoroethylene, or said PTFE.
Parts manufactured using PTFE show high impact strength, wear resistance, and durability coupled with an extremely low friction. In addition, they are heat, moisture, chemical, and radiation resistant. Some of the industrial parts machined using PTFE are:

  • General Industrial PTFE Components as said PTFE parts
  • Chemical handling solutions such as valve bodies, seats & seals, balls, pump and compressor parts
  • Cabling and electrical insulators
  • Semiconductor components applied
  • High temperature electrical parts
  • Components for pharmaceutical & biotech researc
  • Non-lubricated bearings
  • O-rings, seals, and gaskets
  • Gears
  • Valve components, piston o-rings, back-up o-rings, bearings, bushings and gears.
  • Cavity filler seat
  • Ptfe machined parts
