Description: This material consists of 10% Ekonol + 90% pure PTFE, available in cream color.
The hardness is 56 Shore D. PTFE Ekonol exhibits good wear and extrusion resistance, especially in dry-running conditions.
Description: PTFE CF10 is a PTFE compound filled with 10% carbon fiber. The hardness is 58 Shore D. This material is widely used in water hydraulics and is also suitable for softer counter surfaces.
Description: This material consists of pure PTFE, soft carbon, and additives. It is black with a hardness of 60 Shore D.
PTFE E-Carbon offers good dry-running properties and is used, for example, in compressor seals or as lip seals.
Description: PTFE Carbon contains 75% pure PTFE and 25% carbon. It is black with a hardness of 67 Shore D.
The addition of carbon improves creep resistance, hardness, and thermal conductivity of PTFE. This material has excellent wear resistance and is especially suited for use with water.
It serves as the standard material for rotary seals and dynamic seals in hydraulics.
Description: PTFE Graphite with a hardness of 60 Shore D consists of 15% graphite and 85% pure PTFE and is available in dark gray.
PTFE Graphite has one of the lowest coefficients of friction while offering improved thermal conductivity. Wear resistance is particularly excellent when paired with soft metals.
PTFE Graphite is only attacked by highly oxidizing media.
Description: PTFE D46 consists of 46% bronze, 1% pigments, and 53% pure PTFE. It is available in bronze-blue with a hardness of 63 Shore D.
This material has higher strength and lower gap extrusion compared to PTFE II. Its chemical resistance is similar to PTFE II but shows lower wear.
Description: PTFE II, with a hardness of 60 Shore D, is available in brown. The composition is 40% bronze + 60% pure PTFE.
This material offers increased compressive strength and reduced tendency to gap extrusion, combined with good sliding and wear properties. The fillers also provide enhanced thermal and electrical conductivity.
PTFE II is therefore the standard material for hydraulic applications.
Description: PTFE 25% Glass consists of 25% glass fibers and 75% pure PTFE, available in white-gray with a hardness of 60 Shore D.
This material has higher stiffness and better wear properties than pure PTFE. However, PTFE 25% Glass is not suitable for soft counter surfaces and only limited for hot water applications.
Description: PTFE D08 Glass consists of glass, pigments, and pure PTFE. It is orange colored with a hardness of 62 Shore D.
This material is comparable to PTFE 25% Glass but offers better mechanical properties.
PTFE D08 Glass is not suitable for soft counter surfaces and is of limited use in hot water applications.
Description: PTFE D05 Glass is turquoise with a hardness of 60 Shore D. It consists of 15% glass fibers, 1% pigments, and 84% pure PTFE.
This material is comparable to PTFE 25% Glass but has better mechanical properties.
PTFE D05 Glass is not suitable for soft counter surfaces and is limited for use in hot water applications.
Description: PTFE I with a hardness of 58 Shore D consists of 15% glass fibers + 5% MoS2 + 80% pure PTFE and is available in gray color.
This material offers good strength and reduced cold flow (improved creep resistance) at both high and low temperatures. Its wear and friction properties are also superior to pure PTFE.
It is suitable for hydraulic seals in medium-pressure ranges.
Description: This PTFE contains 1% conductive pigment (FDA approved) + 99% pure PTFE. It is available in black with a hardness of 57 Shore D.
The special filler improves conductivity and complies with FDA CFR 21-177.1550.
Description: PTFE D05 is based on pure PTFE with turquoise color (1% pigments + 99% pure PTFE) and has a hardness of 57 Shore D.
Due to the influence of the pigments, this material exhibits higher strength with consistent chemical resistance compared to pure PTFE.
Description: 100% pure PTFE, white, with a hardness of 55 Shore D, is resistant to almost all chemicals except fluorine, molten alkali metals, and halogens.
Pure/virgin PTFE has a low modulus of elasticity and is therefore only slightly mechanically loadable (cold flow, i.e. creep tendency of the material). In addition, pure PTFE has poor thermal conductivity, a high expansion coefficient, and low load capacity as a bearing material. It shows low resistance to abrasive wear.
Seals made from pure PTFE are preferably used in low mechanical stress applications.
