Isocomp Technologies Development

As the need for more demanding uses emerge, PTFE can be customised by the addition of fillers to create PTFE compounds with enhanced physical properties to suit particular mechanical applications outside the scope of virgin PTFE.

By varying fillers and filler content Mechanical, Thermal, Electrical, Chemical and Tribological properties can be tailored.This can be used to achieve results such as:

Improved resistance to cold flow or creep
Reduction in Wear, Friction or Abrasion
Improved dimensional stability
Increased stiffness and surface hardness

An example of Isocomp developing materials is demonstrated with Ticomp S.

Development Case History: TICOMP S

Fluoropolymer composites are now being used increasingly as engineering materials for applications in which tribological properties are important. The overall requirements for a good adhesive wear material is high transfer film ductility and low coefficient of friction.

Ticomp S is a fluoropolymer composite containing reinforcing filaments and lubricants which optimise adhesive wear resistance at loads of up to 4 MPa and surface speeds of 3.2 m/sec.

Ticomp S developed unique advantages over other inorganic and polymer filled materials.

Chemical resistance is excellent, closely matching that of Virgin PTFE
Service temperature under load can be rated up to 210C depending on media, loads and speeds. The excellent thermal stability permits usage in static applications up to 275C continuously or 300C for short duration.
Excellent ductility of the alloy combined with low friction optimises adhesive wear resistance.
The constituents of the alloy are FDA compliant.

Ticomp S can be cost effectively used for static and rotary seals running on softer metal surfaces like stainless steel. Shaft sleeves for vertical spindle and horizontal centrifugal acid pumps are also prime applications. Gaskets and wear strips also benefit from the outstanding properties of Ticomp S
