3M 398FR is a flame-retardant, high-temperature resistant glass cloth tape developed for aviation maintenance environments where heat, flame resistance, and reliability are critical. It is widely used by MRO teams, ground crew, and AOG operations to secure insulation blankets, bundle wiring harnesses, and protect ducts and panels exposed to elevated temperatures.
Designed for durability and flexibility, 3M 398FR performs consistently in high-vibration and extreme temperature conditions typical of aircraft engine and cabin areas. The tape is easy to handle and apply, making it suitable for both scheduled maintenance and urgent repairs while maintaining dependable flame and heat resistance.
Information
Additional Product Information
Description
This flame-retardant glass cloth tape is engineered for use in demanding aviation environments where thermal resistance, durability, and electrical protection are critical. It is commonly used for insulation, wire harness protection, and sealing tasks on both commercial and military aircraft, supporting reliable operation under high heat and vibration conditions.
Technical Characteristics
The tape is constructed from a glass cloth backing with a pressure-sensitive adhesive designed to maintain adhesion and dimensional stability under thermal stress. Typical thickness is approximately 0.25 mm (0.010 in). It supports continuous operating temperatures up to 200°C (392°F) and intermittent exposure up to 260°C (500°F), making it suitable for high-temperature zones within aircraft electrical and insulation systems.
Approvals and Compliance
The material meets recognized flame-retardant requirements including FAA, UL, and MIL-T-15502 standards. It is referenced for use within aircraft electrical and insulation specifications and is associated with major aerospace platforms including Boeing, Airbus, and military programs.
Aircraft MRO and AOG Applications
Typical applications include bundling and insulating wiring looms, protecting electrical harnesses, shielding components from heat and abrasion, and securing insulation materials during scheduled maintenance or unscheduled AOG repairs. Its ease of application and thermal reliability make it suitable for time-critical maintenance environments.
Compatibility and Safety Considerations
The tape is compatible with most aviation-grade wires, cables, and harness assemblies. Its flame-retardant construction helps reduce fire risk in electrical systems and is suitable for use around sensitive avionics and composite structures when applied correctly. Standard PPE practices are recommended during cutting and installation.
Packaging and Logistics
Supplied as a 4-inch (101.6 mm) wide roll with a typical roll length of approximately 36 metres (118 feet). The format allows for straightforward storage and deployment within hangars, maintenance facilities, and AOG response kits.
Specification References
Associated specification references include internal manufacturer code 398FR, FAA and UL flame-retardant compliance, MIL-T-15502, Boeing BMS 5-195 and BMS 5-214, Airbus ABD0031, and applicable Lockheed Martin electrical insulation standards.
Alternative Identifiers
This product may also be referenced under alternative descriptions and identifiers commonly used in procurement and maintenance systems, including flame-retardant glass cloth aircraft tape, electrical harness insulation tape, and various manufacturer and distributor-specific part number formats.
