The combination of a lip made of a PTFE compound combined with the outstanding properties of a shaft sleeve made of solid silicon carbide is the basis for our successful technological concept.

The polymer PTFE is characterized by its low friction, non-adhesion properties and dry running capability (without liquid media). Silicon carbide has the highest hardness of technical materials after diamond and it can quickly dissipate and distribute the frictional heat from the point of its origin in the contact area thanks to its excellent thermal conductivity (5 times better than stainless steel).
