Aerospace series - Sleeving, heat-shrinkable, for binding, insulation and identification - Part 107: Polytetrafluoroethylene (PTFE) - Operating temperatures - 65 °C to 260 °C - Product standard

This standard specifies the required characteristics for a heat-shrinkable, polytetrafluoroethylene sleeving for use in aircraft electrical systems at operating temperatures between ? 65 °C and 260 °C. This sleeving is basically translucent. It is semi-rigid, and suitable for use where resistance to chemicals and high temperature performance are required. It is flame resistant and available in low and high shrink ratios. Type A Low Shrink Ratio; Type B High Shrink Ratio .

Luft- und Raumfahrt - Wärmeschrumpfender Schlauch zur Befestigung, Isolierung und Identifizierung - Teil 107: Polytetrafluorethylen (PTFE) - Temperaturbereich - 65 °C und 260 °C - Produktnorm

Dieses Dokument legt die Eigenschaften für einen wärmeschrumpfenden Schlauch aus Polytetrafluorethylen zur Verwendung in elektrischen Systemen von Luftfahrzeugen bei Betriebstemperaturen zwischen −65 °C und 260 °C fest. Diese Schläuche sind grundsätzlich durchscheinend. Sie sind halbsteif und zur Verwendung an Stellen geeignet, an denen eine Beständigkeit gegen Chemikalien und eine hohe Temperaturleistung erforderlich sind. Sie sind flammbeständig und in niedrigen und hohen Schrumpfverhältnissen erhältlich.
Typ A Niedriges Schrumpfverhältnis
Typ B Hohes Schrumpfverhältnis
