Self-Fusing Mil Spec (Mil-I-46852 & A-A-59163) High-Temperature Silicone Tape
General Information

FlameShieldä Self Fusing Tapes are a Silicone Tape that is self-extinguishing & non-flammable without an adhesive specifically designed for aviation, marine, industrial and commercial use.  Forms an excellent seal that is weather / water / air-tight when wrapped around electrical splices & connections, connectors, cable and wiring splices, hydraulic hose protection sleeves, duct joints and other electro-mechanical devices.

The special silicone formulation of this tape self-fuses (self-amalgamating) when stretched and over-wrapped.  Completely flexible at cold temperatures and can be used to +500ºF / +260ºC continuous exposure.  Does not support combustion and resists heat, flame, solder drips, slag, sparks, Ozone, UV light and contamination.

Can be wrapped over oily or wet surfaces and is an excellent emergency repair tape.  Used extensively as an avionics tape for wire and cable bundling and to protect electrical splices and connectors.

Self-Fusing / Bonding Time

This Self Fusing Tape when over-wrapped under tension adheres to itself and fuses, forming a solid protective shield in 24 hours at room temperature or in just 4 hours at  +356ºF / +180ºC.  The tape starts to self-fuse / self-bond as it is used, and can be re-seated if necessary within a few seconds of over-wrapping.  After a few minutes it is usually necessary to remove the tape with a knife.

Highly Resistant to Harsh Environments

Our self fusing tape resists fuels, oils, acids, solvents, UV, Ozone, high-heat, flame exposure, solder drips & sparks.  The proprietary silicone formulation provides optimal thermal dispersion (high thermal conductivity) and also gives this tape its iron-oxide red color.

Easy & Clean to Use

FlameShieldä Self Fusing Tape incorporates a blue marking stripe along its center, making it easy to over-wrap at 50% when taping long lengths.  The triangular profile of the tape (thickest in the centre and reducing thickness towards each edge) ensures a smooth finish to the installation with minimum ridging.  Easy to remove with a sharp blade while curing or when completely cured and does not leave a gummy or sticky residue the way pressure sensitive adhesive tapes such as standard vinyl electrical tapes or duct tapes do.

How to Install FlameShieldä Self-Fusing Silicone Tape

Lift off the end of the self fusing tape from its backing film and then hold the free end onto what the tape is being installed on.  With your other hand which is holding the remainder of the tape roll, moderately pull or stretch the tape while over-lapping the wrap.  The stretching action activates the special formulation of silicone rubber with the result of the tape self-binding / self-fusing to itself.

Many Practical Uses

FlameShieldä Self Fusing Tapes makes for easy hose and cable bundling, replacing tie-wraps.  Excellent for fixing leaks in piping and hoses.  Makes a good emergency fan belt.  Provides excellent weather protection for outdoor electrical and electronic connections. Great as a first-aid tape to hold splints & bandages in place.

Mil Spec (Mil-I-46852 and A-A-59163) FlameShield™ tape Type I is a rectangular profile tape and Type II is a triangular profile tape.  Type II tape is easier to use and provides a better finish than type I tape when spiral wrapping cables, hoses, pipes or tools.  The triangular profile of the tape (the center is thicker than the edges) provides a smooth edge where the overlap of the tape occurs.  The thinner edges of the type II tape also makes it easier to wrap over curved hoses, pipes or wiring, or over elbows and "T"s.
