Silicone for Aviation & Aerospace

Extreme temperatures and severe pressure differences occur in aviation and aerospace. Utilized silicone products must therefore be resistant to heat and cold and must also not sustain damage in a vacuum. In addition, stringent requirements are placed on the optical and haptic quality. The materials must be permanently color-safe, UV and ozone-resistant. Siltec produces diverse components for furnishing aircraft and helicopter cabins as well as for the production of aircraft. Complete documentation and traceability are a matter of course in this regard. In addition to high design flexibility with respect to color selection and a wide variety of possible Shore A hardness levels, additional features, such as stain-repellant behavior or optimized sliding properties, can be achieved through surface modification.

Fire protection has a central significance in aviation and aerospace. Through the selection of qualified starting materials, fillers, and additives, Siltec ensures that, for example, silicone seals for aircraft interiors have self-extinguishing properties and also that no toxic combustion products arise in the event of a fire. Industry-specific conformities for flammability (e.g. 14 CFR/CS 25.853 (a), Appendix F, Part 1 (a) (1) (ii)) as well as for smoke density according to 14 CFS/CS 25.853 (d), Appendix F, Part V or toxicity according to AITM 3.0005 can be met upon request.

Einsatz von Siltec-Komponenten in der Luft- und Raumfahrt

Examples for the use of Siltec components in aviation and aerospace:

  • Seals for aircraft furnishing, e.g. gap and joint covers, panel seals, smoke seals
  • Components for the production of aircraft, e.g. covers, bump stops, edge protection, resin infusion-molding components
  • Components for aerospace, e.g. seals for robots
  • Other special components, e.g. valves, plugs, spacers for high-performance batteries
