Sealing profiles for aviation
Technical documentation: TU 38 105 1816-87, TU 38 105 1959-90
Application:
- sealing parts made of IRP 1338 rubbers based on SKTV silicone rubber are used for stationary joints operable in air with a high ozone content, in an environment of weak solutions of acids and alkalis; products have a quality certificate.
Conditions of use:
- when exposed to an electric field in the temperature range from -60°С to +250°С.
