Silicone Rubber Self Fusing Electrical Tape - MIL-I-46852 / A-A-59163 / MIL-I-22444


365°F / 180°C Continuous Exposure: Higher Intermittent

FlameShieldä rectangular (Type I) and triangular (Type II) profile silicone rubber self-fusing compression tapes meeting A-A-59163 and Mil-I-46852 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.

MIL-I-22444 tape is available in many colors, but clear, oxide-red and black are the most common.  The tape has a built-in fiberglass sinusoidal reinforcement limiting the amount of elongation (either a maximum of 15% or 25%). Tapes meeting Mil-I-22444 provide superior electrical insulation with a minimum of 350 volts per mil (.001") of tape thickness at 365°F / 180°C. A 20mil tape therefore provides 7000 volts per wrap of insulation value.

This tape is available in almost any color, but oxide-red and black are the most common.  The triangular tape has a guideline stripe in the center which aids in achieving a 50% spiral wrap.  Triangular levelwrap tapes provide a smooth surface on spiral wrapping, preventing the tape wrap area from snagging when pulling a wire or cable through a bundle or over objects or openings.

FlameShieldä tapes meeting A-A-59163 and Mil-I-46852 provide 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.
