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).
General Electric Power Generation A50A493 & 3003M70 Silicone Rubber Self Fusing Tapes
500°F / 260°C Continuous Exposure: Higher Intermittent
FlameShieldä A50A493A, A50A493B, A50A493C, A50A493D, 3003M70P01, 3003M70P02, 3003M70P03 and 3003M70P04 rectangular and triangular profile tapes meeting GE General Electric Power Generation A50A493 & 3003M70 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. All A50A493 tapes are oxide-red in color. 93D is a supported sinusoidal weave glass reinforced tape. 3003M70P01 is oxide-red in color; all other versions (P02, P03, P04) are black.
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.
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.
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.
A50A493A, A50A493B, A50A493C, A50A493D, 3003M70P01, 3003M70P02, 3003M70P03 and 3003M70P04 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.
