In general, though, most types of electrical tape will start to show signs of degradation at around 70°C.
Several grades of vinyl electrical tape are available — all of which differ in conformability, ease of unwinding, resistance of the adhesive to heat and cold, and loosening (flagging). While general-use vinyl tapes are appropriate for bundling, wire pulling, and other ancillary tasks, premium-grade vinyl tape is the best choice for permanent insulation work as it handles the broadest range of environmental factors and functions, such as cold weather.
Tape also serves as a valuable tool for protecting surfaces during construction Fire-resistant adhesive tape is made with materials that have inherent flame-retardant properties. These materials, often including ceramic fibers, intumescent compounds, or heat-resistant polymers, are formulated to slow down or prevent the spread of fire. They are engineered to maintain their adhesive strength even under extreme heat, ensuring they can effectively seal, insulate, and protect surfaces from fire's destructive force.
