Thin double sided tape electronics12/14/2023 Kapton-wire degradation and chafing due to vibration and heat has been implicated in multiple crashes of both fixed wing and rotary wing aircraft, with loss of life. Many aircraft models have had to undergo extensive rewiring modifications-sometimes completely replacing all the Kapton-insulated wiring-because of short circuits caused by the faulty insulation. It was found to have very poor resistance to mechanical wear, mainly abrasion within cable harnesses due to aircraft movement. 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 In isolation, Kapton remains stable 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 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.
