Black Insulation Tape

Insulation tape is a type of pressure-sensitive tape that you can use to insulate electrical wires and other materials that conduct electricity. Manufacturers make it of many plastics, but PVC (polyvinyl chloride, “vinyl”) is most popular. This is because it stretches well and gives an effective and long lasting insulation.

Today, electrical tape is simply “another form of insulation”. They manufactured original electrical insulating tape with cloth tape impregnated with Chatterton’s compound. This was an adhesive material manufactured using Gutta-percha. They often used this type of tape to insulate soldered splices on knob and tube wiring. They commonly referred to it as “friction tape”, and had the unique property of being sticky on both sides. Because of this, no matter how you used it it stuck to itself very readily.

In the early 1940s, vinyl plastic emerged as a versatile material for a wide range of applications, from shower curtains to cable insulation. A major ingredient in vinyl film was tricresyl phosphate (TCP). They used this as a plasticizer. Unfortunately, TCP tended to migrate, giving the surface of the vinyl film an oily quality and degrading every tape adhesive known. Research chemists and engineers at 3M set out to create a dependable, pressure-sensitive tape made of vinyl film that would have the required electrical, physical and chemical properties.
