DKI can offer a wide range of PTFE compounds for applications requiring minimum friction,

wide temperature range and maximum media resistance.



Our range includes Virgin PTFE and mixes of carbon, graphite and glass filled PTFE compou-

nds.



Suited for many applications, our PTFE compounds are available in o-ring, wiper, rod and pi-

ston profiles, as well as spring loaded seals, guiding/bearing elements and custom designs.

Benefits include



   -Low friction 



   -High wear resistance



   -High temperature resistance



   -Aggressive chemical resistance 



PTFE  Seals are available in the following 
material specification: 



Virgin PTF



 Used mainly for o-rings, backup rings and machined parts
 used in special applications requiring chemical inertness a-
 nd limited strength. Ideal for use in cryogenic applications. 



Bronze filled PTFE



 Typical application: Used in dynamic sealing applications where the bronze filler gives improv-
 ed wear resistance, hardness and compressive strength. The electrical properties and chemic-
 al resistance are reduced. Molybdenum disulphide improves the self lubrication.  



Graphite filled PTFE



 Typical application: Significant increased thermal conductivity, reduced level of creep. Self lub-

 ricating, therefore suitable for high speed applications, without the need for exterior lubrication

 and applications which need to remove thermal energy and/or static electricity. 



 Glass filled PTFE



 Typical application: Used where there is a need for improved wear and increased coefficient 

 of friction. Ideal for high dynamic applications e.g. high rotation pumps.
