PTFE Materials

PTFE materials have an excellent chemical compatibility. Due to the fact that PTFE itself does not have a memory or tendency to move back to its original shape, a energizes is often required. Its chemical compatibility and wear resistance makes it an excellent material for dynamic and high demanding static applications.

NDS-100

Virgin PTFE is the most elastic type with high chemical resistance. Commonly used in Food and chemical applications.

  • Temp range:
    -190 to +230 °C
  • Color:
    White

NDS-123

PTFE with glass and Molybenumdisulfide. Reduced starting coefficient of friction, increased wear resistance and hardness make this an excellent solution for medium duty dynamic applications.

  • Temp range:
    -190 to +290 °C
  • Color:
    Black

NDS-150

PTFE Blue. Improved wear resistance used for low duty hydraulic applications.

  • Temp range:
    -190 to +230 °C
  • Color:
    Blue

NDS-225

PTFE + 25% Carbon. Improved wear and creep resistance. Adding carbon to PTFE significantly increases the thermal conductivity.

  • Temp range:
    -190 to +315 °C
  • Color:
    Black

NDS-235

PTFE + 10% carbon fibre. Improved wear and creep resistance. Excellent sliding properties in water.

  • Temp range:
    -260 to +310 °C
  • Color:
    Black

NDS-415

PTFE + 15% graphite. Lowered coefficient of friction and excellent self lubricating properties. Excellent for use in soft shaft/sealing surfaces.

  • Temp range:
    -190 to +230 °C
  • Color:
    Grey

NDS-640

PTFE + 40% bronze. Outstanding wear and creep resistance. Ideal for use in heavy mechanical and hydraulic applications. Reduced chemical resistance and possible oxidation needs to be notices.

  • Temp range:
    -156 to +260 °C
  • Color:
    Bronze

NDS-660

PTFE + 60% bronze. Outstanding wear and creep resistance. Ideal for use in heavy mechanical and hydraulic applications. Reduced chemical resistance and possible oxidation needs to be notices.

  • Temp range:
    -156 to +260 °C
  • Color:
    Bronze

NDS-750

PTFE + Polyimide. Highly abrasion resistant and low friction of coefficient. Excellent for use in dry running and high speed applications.

  • Temp range:
    -260 to +310 °C
  • Color:
    Tan
