![]() Kapton insulation ages poorly: an FAA study shows degradation in hot, humid environments or in the presence of seawater. The thermal conductivity of Kapton at temperatures from 0.5 to 5 Kelvin is rather high for such low temperatures, κ = 4.638×10 −3 T 0.5678 W Kapton remains stable (in isolation) across a wide range of temperatures, from 4 to 673 K (−269 to +400 ☌). Kapton E offers reduced coefficient of thermal expansion (CTE), reduced moisture absorption, and reduced coefficient of hygroscopic expansion (CHE) compared to Kapton H. The BPDA component adds greater dimensional stability and flatness in flexible circuitry applications. Kapton E is a mix of two dianhydrides, PMDA and biphenyltetracarboxylic acid dianhydride (BPDA), and two diamines, ODA and p-phenylenediamine (PPD). It is produced from the condensation of pyromellitic dianhydride (PMDA) and 4,4'-oxydiphenylamine (ODA). The chemical name for Kapton K and HN is poly (4,4'-oxydiphenylene-pyromellitimide). The ring closure is carried out at high temperatures of 470–570 K (200–300 ☌). The intermediate polymer, known as a poly(amic acid), is soluble because of strong hydrogen bonds to the polar solvents usually employed in the reaction. Kapton synthesis is an example of the use of a dianhydride in step polymerization. The name Kapton is a registered trademark of E. Kapton remains manufactured by DuPont to this day. Kapton was invented by DuPont in the 1960s. Its favorable thermal properties and outgassing characteristics result in its regular use in cryogenic applications and in situations where high vacuum environments are experienced. Kapton is used in electronics manufacturing, space applications, with x-ray equipment, and in 3D printing applications. Invented by the DuPont Corporation in the 1960s, Kapton remains stable (in isolation) across a wide range of temperatures, from 4 to 673 K (−269 to +400 ☌). Kapton is a polyimide film used in flexible printed circuits ( flexible electronics) and space blankets, which are used on spacecraft, satellites, and various space instruments. Kapton and ABS adhere to each other very well, so is often used as a build surface for 3D printers.Kapton insulating pads for mounting electronic parts on a heat sink.As very high temperature mask during powder coating applications. ![]() capacitor and transformer wrapping/insulation.Electrical for coil insulation, Splicing wires.Electronics for Masking Circuit Boards in wave soldering(and in gold leaf masking).Some of Kapton tape's primary use cases are: Wave soldering during circuit board assembly.consumer electronics, solar photovoltaic and wind energy, aerospace, automotive and industrial applications.You can put a soldering iron on Kapton tape and it will not melt.Īpplications in a range of industries including, Kapton tape (generally known as polyamide tape) is a cool tool in these cases and better that regular black electrical tape for most applications Silicon adhesive protection leaves no residue.Unique properties of Kapton Polymide film Tape Kapton is used in, among other things, flexible printed circuits and space blankets, which are used on spacecraft, satellites, and various space instruments. Kapton is a polyimide film developed by DuPont in the late 1960s that remains stable across a wide range of temperatures, from −269 to +400 ☌. Temperature range up to 500 Degrees Fahrenheit.
