The first commercially available version of the tape was sold for use as a wire-harness wrapping. This original electrical tape wasn't black. [5] Tapes formulated for high-temperature were yellow, and later versions were white. Electrically insulating tapes are essential for enhancing functionality and reliability in a wide range of applications.
Quarter inch cartridge tape (abbreviated QIC, commonly pronounced "quick") is a magnetic tape data storage format introduced by 3M in 1972, [1] with derivatives still in use as of 2016. QIC comes in a rugged enclosed package of aluminum and plastic that holds two tape reels driven by a single belt in direct contact with the tape.
Normally, a thermostat is used to energise when it measures temperature falling below a set temperature value - usually between 3 °C and 5 °C and often referred to as the 'setpoint'. The thermostat will de-energise the trace heating when it measures temperature rising past another set temperature value - usually 2 °C higher than the setpoint ...
This means that the tape changes length by 1.16 mm per 10 m tape per 10 °C change from the standard temperature of the tape. For a 30 meter long tape with standard temperature of 20 °C used at 40 °C, the change in length is 7 mm over the length of the tape.
This tape is used extensively in aviation and aerospace wiring applications as a splice or wrapping tape due to its non-flammability. [citation needed] It can be used for emergency repair of leaking low-pressure hoses and pipes. Compared to most other electrical and utility tapes, centerline tape is not particularly tough mechanically.
Magic Tape, also known as Magic Transparent Tape, is a brand within the Scotch Tape family of adhesive tapes made by 3M, sold in distinctive plaid packaging. Invented and introduced in 1961, it is the original matte finish tape. It appears frosty on the roll yet is invisible on paper. This quality makes it popular for gift-wrapping. [13]
