PTFE - Moulded Products

Moulded PTFE Rods

Moulded PTFE (unfilled or virgin) Rods are generally used as machining stock for all kinds of chemical, electrical and mechanical components. These rods are used to make seals, washers, back up rings and many other such components.

PTFE powder is blended along with the fillers to strengthen the core properties, various fillers are available to further modify the properties to meet critical applications.

Standard available compositions:

  • Virgin PTFE – excellent chemical, thermal and non-frictional / abrasion resistant properties
  • Filled PTFE – PTFE powder is blended along with the fillers to strengthen the core properties
    • 15% & 25% Glass
    • 25% & 35% Carbon
    • 15% & 25% Graphite
    • 40% & 60% Bronze
    • PEEK
    • 55% Bronze + 5% Molybdenum Sulphide (MoS2)
    • 15% Glass + 5% Molybdenum Sulphide (MoS2)
    • Stainless steel
    • Mica

NOTE: Custom sizes and lengths and larger diameters can be made upon request.

Moulded PTFE rods are available in stock at all times and can be supplied in various standard sizes.

Standard sizes available:

Rod Size AvailableDiametersLengths
4 mm upto 300 mm150mm, 300mm & 1000 mm

NOTE: Custom sizes and lengths and larger diameters can be made upon request.

Moulded PTFE Sheets

PTFE is the most chemically resistant plastic of all known polymers. PTFE sheets also provide a low-friction, non-stick surface suitable for use in high temperature and have a very low water absorption rate.

HI-TECH offers moulded PTFE sheets, which are manufactured by the compression moulding processes using PTFE granular resin followed by the sintering process which sets it. The sheets have characteristics of a wide range such as:-

  • Wide operating temperature range from -260°Celcius up to +260°Celcius
  • Chemical corrosion resistance
  • Weathering resistant
  • Dielectric superiority

Available:

  • Chute Liners
  • Lining for conveyors
  • Dip tubes
  • Vessel and Tank Liners

Standard available compositions:

  • 15% & 25% Glass
  • 25% & 35% Carbon
  • 15% Graphite
  • 40% & 60% Bronze
  • PEEK
  • 55% Bronze + 5% Molybdenum Sulphide (MoS2)
  • 15% Glass + 5% Molybdenum Sulphide (MoS2)
  • Stainless steel
  • Mica

Compression moulded sheets are usually available in higher thicknesses. The sheets can be supplied in standard sizes as well as specific cut size requirements.

Standard available sizes:

Standard available sizesSheet dimensions (width x length)Thickness
300 mm x 300 mm3mm upto 100mm
600 mm x 600 mm
1000 mm x 1000 mm
1000 mm x 2000 mm

NOTE: Custom sizes can be made / cut upon request.

Moulded PTFE Tubes / Bushes / Cylinders

Moulded PTFE (unfilled or virgin) cylinders are generally used as machining stock for all kinds of chemical, electrical and mechanical components. These tubes are used to make components such as seals, solid and envelope gaskets, which are used in various industries such as chemicals and oil and gas.

Using our advanced compression moulding process, we make PTFE cylinders with a high quality surface finish, free from stress, and close to the dimension of the end product, which in turn helps maximizing economy and minimizing machining and reducing material loss.

Applications:

  • Different types of Seals (Mechanical, pneumatic)
  • Washers
  • Guide Rings

Standard available compositions:

  • 15% & 25% Glass
  • 25% & 35% Carbon
  • 15% Graphite
  • 40% & 60% Bronze
  • PEEK
  • 55% Bronze + 5% Molybdenum Sulphide (MoS2)
  • 15% Glass + 5% Molybdenum Sulphide (MoS2)
  • Stainless steel
