Product features

DOCAFLON PTFE-N is the unreinforced, unfilled version. It is mainly used in applications with low mechanical stress, where chemical resistance, sealing or low friction are required. DOCAFLON PTFE-N is manufactured using different production technologies, which affects the size range.

DOCAFLON (PTFE, Teflon) product family features

The PTFE, or Teflon, product range is unavoidable due to its outstanding chemical resistance and temperature tolerance. It is a soft and flexible material, but with a high density, taking into account its low dimensional stability. It is excellent for sealing and gasketing, as well as in conditions (e.g. hot, chemical media, steam) where only alternatives to Teflon would be orders of magnitude more expensive. It is available in sheet, film, rod and tube formats, e.g. from 4 mm to 300+ mm diameters in rod.

In addition to the basic version (natural Teflon or natural PTFE), we can offer a wide range of sizes of glass fibre version (glass fibre PTFE, standard version 25% containing glass fibre: PTFE GF25) and carbon fibre version, which is antistatic, electrically non-insulating (ESD Teflon, also known as PTFE CG25 or graphite Teflon).

Some important features

Highly chemically stable
Tensile strength: 16-25 MPa
Good ability to choose the form
Good machinability
Wide application temperature range: from -200°C to +260-300°C,
Hardness (Rockwell): D 50 - D 75
Good damping capacity, tough
Low friction coefficient
Poor adhesion (grip)
Physiologically neutral, may come into contact with food and medicines
Good electrical insulation in wet media

Main areas of application

Food, chemical and textile machinery parts
General seals, insulating elements
Precision instrumentation components
Medical, pharmaceutical equipment
Sliders, formwork dividers, etc.

Machining technology

Chipping (turning, milling, drilling, sawing): traditional metalworking tools, in some cases woodworking tools - carbon steel, high-speed steel, carbide, diamond - can be used, but only with a sharp finish. Cooling is recommended to allow high cutting speeds (e.g. v = 200-400 m/min for turning and milling, v = 50-100 m/min for drilling).

Gluing: is not recommended.
