We hope this article was able to answer your questions on electrical tape being heat resistant!

The first commercial tape for electrical insulation was cotton friction tape, which became available in the early 1930s. Vinyl electrical tape was introduced in the mid 40s. This advanced material provided dramatic advantages over friction tape, including improved adhesion and moisture protection. Vinyl tapes have been refined substantially over the years, and other tape products have been added as well. Today's tapes offer long-term performance, excellent adhesion, and temperature resistance — not to mention smooth unwind from the roll. Resistance to adhesive transfer, superior conformability, high tensile strength, good elastic memory and recovery, and wider installation and operational temperature ranges characterize premium products.

At its core, insulation tape is designed to insulate electrical wires and other conductive materials. The 50mm width makes it especially suited for larger cables and applications where broader coverage is necessary. Typically made from a blend of PVC and rubber, black insulation tape is favored for its durability and resistance to electric current, heat, and moisture. The black color also provides a sleek look that blends well with many surfaces, making it ideal for both visible and hidden applications.

Another noteworthy property is its excellent elasticity and flexibility, which ensures that it can be easily manipulated into different shapes and sizes. Butyl rubber also exhibits good fire resistance and remains functional even at extreme temperatures, ranging from -20°C to 150°C. These properties make butyl rubber rolls not only durable but also suitable for a variety of demanding applications.
