PTFE is a synthetic fluoropolymer of tetrafluoroethylene that has a wide range of applications. Especially where no high mechanical strength is required and where the use of compounds is not allowed. The best known brand name of PTFE-based formulas is Teflon® by Chemours®.

PTFE virgin & compounds

Because of its purity, inertness, high temperature resistance and electrical isolating properties, PTFE finds most of its applications in the chemical, food, pharmaceutical and electrical industry. A large variety of compounds can be added to improve the properties of virgin PTFE for a specific application. This can bring improvements on mechanical strength, wear, friction, conductivity, heat dissipation …

PTFE + 15% GLASS OR PTFE + 25% GLASS

PTFE_MaterialsGlassfilling slightly increases PTFE’s very low coefficient of friction, but considerably increases wear and pressure resistance. The best results are obtained by using Dyneon TFM® as basic material. Used as construction material for bearing pads, ball seals …

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 + 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 dynamic seals.

CARBON FIBER

Same as carbon/graphite, but with improved stiffness, reduced creep and reduced thermal expansion. Used for valve seats, bearings … Allowed for steam applications.

PTFE + 15% GRAPHITE

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

PTFE VFG - VX1 - MAROON

The high concentration of glass fibers, combined with the addition of inert metallic oxides make this compound your best choice, where pressure and wear resistance are of major importance. Used for seals that require very low cold-flow abilities.

STAINLESS STEEL

High compression resistance, only for low PV values. Used for seats in steam valves.

SUMICASUPER 10% EKONOL

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

PTFE + 60% BRONZE

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

P84 - POLYIMID

Exceptional filler component to improve PV values. Used for lip seals, rotary shaft seals …
