Crossflon® XF225 is an enhanced form of PTFE, which offers substantially improved performance over the materials traditionally used in the manufacture of skidway plates and slide bearings, namely virgin and 25% glass fibre filled PTFE.
As the technical data shows, Crossflon® XF225 can accommodate significantly higher pressure than 25% glass fibre filled PTFE and yet has coefficient of friction values which are comparable with those of virgin PTFE.

|---|---|---|---|
| MATERIAL | VIRGIN PTFE | 25% GLASS FIBRE FILLED PTFE | CROSSFLON® XF225 |
| DESCRIPTION | A PTFE material that has a low coefficient of friction and high chemical inertness. Suitable for a very wide range of applications that require these characteristics. | A reinforced PTFE material that has high compressive rigidity, low cold, high wear resistance and good chemical resistance. For use in most applications involving sealing and bearing. | A reinforced PTFE material that has a low coefficient of friction, high creep resistance, high load bearing capability and high wear resistance. Specifically developed for skidway and slide bearing applications. |
