- Extremely low coefficient of friction static and dynamic
- Extremely low stick-slip effect
- Excellent wear resistance even in dry applications
THERMAL PROPERTIES
- Stable behavior at operating temperatures from -240° C to +260° C and for short time up to +280° C
- Dimensional stability
- Excellent thermal dissipation capacity ( specific grades )
CHEMICAL PROPERTIES
- Excellent chemical inertness
- TEKSLIDE materials can operate in salt water, in steam environment or aggressive and corrosive chemical environments
- Good gas proof properties (specific grades)
ELECTRICAL PROPERTIES
- According to different grades of TEKSLIDE materials the following properties can be enhanced:
- Good dielectric properties (insulation)
- Excellent conductivity properties for antistatic applications
MECHANICAL PROPERTIES
- Extremely high PV and sliding behavior
- High load compression resistance (radial/axial)
- Low abrasive surface for applications on soft countersurfaces
- Excellent vibration dampening and noiseless
OTHER TYPICAL PROPERTIES
- Flexibility and fatigue stress resistance
- Some of the TEKSLIDE materials are atoxic and excellent for food contact and food industry applications

Bearing Tapes
All kinds of bearings are available in standard materials as well as G471, G461 and G464, for the heaviest applications in the hydraulic, motion control and mechanical fields. They’re made by special PTFE compounds and technologies, in order to fulfil GUARNIFLON’s customers’ requirements.
Special fillers are selected to enhance properties such as:
- wear resistance
- coefficient of friction
- compression strength
Thickness from mm. 1,5 to mm. 5
Width from mm. 4 to mm. 300
Rings
Whenever the chemical and thermal resistance of standard rings in static applications like static seals or flange connections is no longer sufficient, PTFE rings are the solution. Standard dimensions as well as special dimensions under customer specifications are available.
Tapes
Most materials can be skived thanks to the technologies available nowadays in GUARNIFLON® up to mm. 6 according to customers’needs. TEKSLIDE tapes show excellent performance for applications where friction reduction is required.
Machined Products
Automatic turning machines as well as CNC machines can produce more than 1.5 million pieces per day. To ensure high and stable quality standards, GUARNIFLON® is running the electronic system S.P.C. (Statistical Process Control).
Etching Technology for Bounding Purposes
Guarniflon® owns the most updated technologies dedicated to the etching process on semifinished and finished products. The etching process of GUARNIFLON® is capable of providing uniform reactive surfaces.
