PTFE compounds
Why use a PTFE compound?
A large variety of compounds can be added to improve the properties of virgin PTFE for a specific application.
Fillers are incorporated into PTFE for the following reasons :
- to increase wear resistance
- to reduce cold flow under load
- to increase thermal conductivity
- to reduce thermal expansion
- to change electrical insulation properties
- etc.
Vanéflon can supply a vast range of standard PTFE compounds : PTFE filled with glass, carbon, Sumikasuper, graphite, bronze, stainless steel, PI, etc. As we have more than 100 standard PTFE compounds in stock, we can supply you very quickly.
Vanéflon can even develop specific custom-made PTFE compounds for specific applications.

VIRGIN PTFE
is used in a wide range of applications where no high mechanical strength is required and where the use of compounds is not allowed
Applications: chemical-, food-, pharmaceutical- and electrical industries.
mPTFE (Modified PTFE – TFM)
same as virgin PTFE but improved creep resistance and reduced porosity. Excellent weldability.
Applications: coated valve discs, valve seats, linings, etc.
PTFE + GLASS
increases resistance to wear and pressure.
Applications: construction parts, bearing pads, ball seats, etc.
PTFE + GRAPHITE
good thermal conductivity and excellent lubrication properties
Applications: bearings, sliding pads, etc.
PTFE + CARBON
high heat conductibility and high resistance to wear and pressure.
Applications: compressor rings, piston rings and other dynamical seals, etc.
PTFE + BRONZE
high pressure resistance and low coefficient of friction.
Applications: bearings, etc.
PTFE + SUMIKASUPER
improved mechanical properties without increasing porosity
Applications: lip seals, shaft seals, etc.
PTFE + STAINLESS STEEL
high compression resistance, but only for low PV-values
Applications: seats in steam valves
PTFE + POLYIMIDE (P84)
exceptional filler component to improve PV-values
Applications: lip seals, rotary shaft seals, etc.
PB72
identical to P84 but improved thermal conductivity and higher PV-values. FDA approved.
Applications: lip seals, rotary shaft seals, etc.
