PTFE

VIRGIN PTFE

Has a wide range of applications. Especially where no high mechanical strength is required and where the use of compounds is not allowed.

Because of its purity, inertness, high temperature resistance and electrical isolating properties, PTFE finds most of its applications in chemical-, food-, pharmaceutical- and electro-industry.

Major PTFE compounds include:

PTFE + 15% GLASS or PTFE + 25% GLASS

Glassfilling slightly increases PTFE’s very low coefficient of friction, but considerably increases wear- and pressureresistance. The best results are obtained by using Dyneon TFM as basic material. Used as constructionmaterial, for bearing pads, ball seals, etc.

PTFE + 17% GLASS + 3% MoS2

Shows the same pressure resistance as glassfilled PTFE but uses MoS2 as a lubricant.

Molybdenum also increases hardness and decreases wear.

PTFE VFG - VX1 - MAROON

The high concentration of glass-fibres, combined with the addition of inert metallic oxides make this compound to be your best choice, where pressure- and wear-resistance are of major importance.

Used for seals that require very low cold-flow abilities.

PTFE + CARBON/GRAPHITE 22/3

Carbon is one of the best fillers for chemical use. It features high heat-conductibility and high wear- and pressure-resistance Recommended for piston-rings and other dynamical seals.

CARBON FIBER

Same as Carbon/Graphite with improved stiffness, reduced creep and reduced thermal expansion. Used for valve seats, bearings etc. Allowed for steam applications.

PTFE + 15% GRAPHITE

A compound with excellent thermal- and electrical conductivity. For antistatic linings and bearings.

SUMICASUPER 10% EKONOL

Exceptional filler component to improve the mechanical properties without increasing the porosity. Used for lip seals, back-up rings etc.

PTFE + 60% BRONZE

This compound combines a low coefficient of friction with a high pressure resistance. Both these properties make this a bearing-material by excellence.

P84 - POLYIMID

Exceptional filler component to improve PV-Values. Used for lip seals, rotary shaft seals etc.

PB72

Same applications as P84, but improved thermal conductivity and higher PV-values. FDA-compliant.
