| Résumé : |
Due to its high melt viscosity and its melting point of over 327 °C, polytetrafluoroethylene cannot be processed by common thermoplastic processes. However, appropriate modification makes this high-performance plastic workable from the melt, thereby enabling economical large series production. This will be elaborated here on two sealing applications. |

- Spring-supported seal
- Sealing lip from PTFE compound
- Combined PTFE and PEEK
- Fig. 1. A spring-supported seal for a ball segment used in an engine cooling water circuit. It is made from modified PTFE, processed by injection molding, and demonstrates the usefulness of this material - for medicinal areas as well
- Fig. 2. This component is instsalled in housing covers in a vehicle engine compartment. It consists of a front cover made from 30% glass-fiber-reinforced polyamide with an encapsulated sealing lip made from a PTFE compound. It also contains a metal insert and is designed for rapid installation. |
