CARBON FILLED PTFE EXCELLENT MECHANICAL AND WEAR PROPERTIESCarbon Filled PTFE was developed to provide a PTFE based material with improved mechanical strength.PTFE on its own has excellent frictional properties, elasticity and wear resistance but relatively poor mechanical strength and tends to fail in high PV applications.??CARBON FILLED PTFE PROPERTIESCarbon in itself is a brittle material with poor wear properties and mechanical strength. However with the two combined in Carbon Filled PTFE formulations, the resultant material has excellent mechanical and wear properties, retains the excellent frictional properties and is an excellent choice for seals and rings in dynamic and high pressure applications.Carbon filled PTFE also provides good thermal conductivity, low permeability and is also electrically conductive making it a good choice for anti-static applications??POSSIBLE VARIATIONSThe most common carbon filled PTFE composition is 75% Virgin PTFE with 25% Carbon powder by weight.When a filler ratio or type is unspecified, it is fair to assume this is the material. However it doesn t tell the whole story. The type and percentage of carbon added to PTFE is a variable and is critical to material performance.It can be as little as 0.2% and as much as 40%.??Different percentages of carbon will display different material properties and performance.Something that??is often overlooked is that different types of carbon powder can also affect the material integrity and performance. To achieve the optimum physical properties and performance from any filled PTFE it is essential that the properties and type of fillers used are understood.Not all 25% carbon filled PTFE materials are the same, in fact they can be extremely different.STRENGTHS???Good thermal and electrical conductivity???Good chemical resistance???Very economical???Improved wear resistance under loadWEAKNESSES???High percentage fillers mean low elongation???Conductivity can be a problem

The addition of Bronze to PTFE gives better dimensional stability and lowers creep, cold flow and wear. It increases hardness and compressive strength whilst also increasing thermal and electrical conductivity.
 
BRONZE FILLED PTFE PROPERTIES
Bronze Filled PTFE is reinforced with bronze powder with the percentage varying between 40% and 60%, resulting in a very hard wearing material. It has weaker chemical resistance than other grades of PTFE and isn''''t suitable for electrical applications.
STRENGTHSExtremely hard wearing materialVery heavy – high specific gravityElectrically conductiveWEAKNESSESNot suitable for electrical applicationsPoor chemical resistance

The superior coating has the needed strength along with the dimensional stability of the fiberglass. Moreover, it offers easy release and has heat resistance of PTFE. It features comparatively heavier coating of PTFE.
