Lockheed-Martin Tactical Systems P5189 Silicone Rubber Self Fusing Tapes
500°F / 260°C Continuous Exposure: Higher Intermittent
FlameShieldä sinusoidal weave glass supported tapes meeting Lockheed-Martin Tactical Systems P5189 specification are used for a variety of critical electrical wiring and cable splicing and protection jobs. Especially suited for aviation and marine environments, as well as outdoor weathering environments.
The tape has no adhesive, but sticks to itself (self-fuses or self amalgamating) when stretched and wrapped onto itself. The tapes starts curing within minutes, and after several hours cannot be unwound or removed without using a sharp knife or blade. This tape makes a waterproof, weatherproof and air tight protection.
This tape is specified as oxide-red in color; however variants are available in black if required.
Provides superior electrical insulation with a minimum of 300 volts per mil (.001") of tape thickness at 365°F / 180°C. A 20mil tape therefore provides 6000 volts per wrap of insulation value.
This tape is also used to wrap hydraulic connections and to make vibration resistant bumpers and spacers for wiring, cable, hose, pipes and lines. This tape is used to wrap and hold insulation in place on hot air ducts. Makes an in-situ bushing for protecting wiring at the backshell clamp.
