Our PTFE technology

PTFE - even without lubrication - excels at offering an exceptionally low coefficient of friction in combination with metals and plastics

PTFE is highly anti-adhesive, without any stick-slip effect

PTFE has high elongation properties enabling easy fitting of sealing and guide elements to one-piece pistons

PTFE - when subject to moderate stress - offers an exceptionally wide (for plastics) thermal operating temperature range depending on application from -260°C to +260°C

PTFE is chemically resistant to nearly all solid, liquid and gaseous media

PTFE is age-resistant, non-combustible and physiologically neutral in the state temperature range

Benefits of the PTFE Coated Piston Compared with Standard Guide Bands and Rider rings

The specific surface pressure is reduced by coating the entire piston skirt all the way to the seal groove. By maintaining a low radial section of the bearing element, thermal expansion is reduced allowing significantly lower running clearances to be specified.

Reduced running clearance largely prevents piston slap, resulting in significantly smoother operation

Improved heat transfer from the piston to the cylinder wall due to the low coating thickness and large contact surface area
