Our seals and engineering solutions made of PTFE and other high-performance plastics have been used in large aircraft programs for many years.

Decisive Advantages

Not only can high-performance plastics be designed with precisely the required properties, they also offer explicit advantages for the aviation industry:

  • Broad thermal application range
    (–250°C to +260°C)
  • Almost universal chemical resistance
  • Light- and weather-resistant
  • Very good sliding characteristics (no stick-slip effect)
  • Nonflammable LOI > 95
  • Good electric and dielectric properties
    (dielectric loss factor tan δ = 0.3x10-3 (25 GHz);
    extremely low dielectric constant ξr = 2.0 to 2.1)
  • No water absorption (0.01%)
