Silicone Tapes

All tapes meet 14 CFR 25.853(a) at amendment 25-116; Appendix F, Part I(a)(1)(i) (60 Second Vertical Flammability Test).

MIL-I-22444C MIL Spec Silicone Rubber Self Fusing Electrical Tape with Sinusoidal Weave Glass Support Reinforcement

500°F / 260°C Continuous Exposure: Higher Intermittent

The FlameShieldä line of MIL-I-22444 silicone tapes covers 5 tape options with a total of 24 variants. The options are Width, Thickness, Elongation, Color and Roll Length. The most commonly ordered and popular versions ares 1" wide, 0.020" thick, in 15% or 25% limited elongation and in Oxide-red or Black color. If you need assistance in choosing a variant please read our FAQ or contact our Technical Support.

FlameShieldä rectangular profile silicone rubber tapes with sinusoidal weave glass support reinforcement meeting Mil-I-22444C 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 embedded sinusoidal fiberglass layer provides limited stretch of the tape during installation, ensuring that a consistent minimum thickness is achieved during installation opposed to a variable thickness that occurs when manually adding tension to the tape during human applied scenarios. Machine applied tape tends to be much more uniform in thickness due to the automated tensioning measurement feedback in the application machinery.

Supported/reinforced tape also prevents tape creep and fracturing when the tape is clamped with excessive force with either a connector back-shell, or installation clamp on a hydraulic fitting. The tape tends to remains in place and without layer fracturing compared to non supported/reinforced versions of the tape (MIL-I-46852 and A-A-59163 versions).

MIL-I-22444C 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-22444C 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-22444C 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 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 back-shell clamp.
