PTFE is a semi-crystalline polymer made of fluorine and carbon that is most well-known under the brand name Teflon® from DuPont.
For manufacturing purposes, PTFE in powder form is sintered to create semi-finished PTFE parts or finished PTFE parts.The incorporation of filler material (e.g. bronze, fiberglass, carbon/graphite) makes it possible to adapt the physical characteristics of the material to meet the specific application requirements. In general, the surface of PTFE exhibits a low friction coefficient along with a high level of resistance against aggressive chemicals and can be used in applications with a very wide temperature range.
Coating O-rings with PTFE. In this process, the elastomer core (generally FKM/VMQ/EPDM) is coated with one or more thin layers of PTFE. Position of impact and the number of layers (e.g. single/double coating) by arrangement. Application example: as a component in mechanical seals
Machining production of customer-specific parts made of semi-finished PTFE products. Application example: support rings, O-rings
Flat gaskets can be used to statically seal two sealing surfaces. Production is carried out based on the parts in question, e.g. using machining, sintering or punching semi-finished PTFE products.
