This specification covers an irradiated, thermally-stabilized, flame-resistant, modified silicone rubber in the form of heat shrinkable tubing. Primarily for use as a flexible, electrical insulation tubing whose diameter can be reduced to a predetermined size by heating to 175 °C (347 °F) or higher. This tubing is stable under the following conditions: -70 to +180 °C (-94 to +356 °F) Continuous; -70 to +300 °C (-94 to +572 °F) 4 hours.
The following specification designations and their properties are covered: AS7478: 130 ksi minimum ultimate tensile strength at room temperature 65 ksi stress-rupture strength at 1200 degrees F; AS7478-2 130 ksi minimum ultimate tensile strength at room temperature 78 ksi minimum ultimate shear strength at room temperature.
Classification: 130 ksi minimum tensile strength at room temperature 1200 degrees F maximum test temperature of parts.
Primarily for aerospace propulsion system applications where stress-rupture strength and creep resistance are required at elevated temperature.
SCOPE IS UNAVAILABLE.
