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. 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 °C).
Chemical structure of Kapton, a polyimide. Polyimide (sometimes abbreviated PI) is a polymer containing imide groups belonging to the class of high-performance plastics.With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, such as high temperature fuel cells, displays, and various military roles.
That bunker housed a shooting range that was used to test DuPont powders and other explosives. In later years, it housed a golf ball cannon and high speed photography equipment to measure the Coefficient of Restitution of golf balls made with various DuPont elastomers. Building 256. Surlyn ionomeric resins. Teflon FEP Fluorinated ethylene propylene
In 1955 DuPont developed Kapton, a polyimide plastic film which did not suffer from aluminium's deficiencies, so Kapton, and later Kaneka Apical were widely adopted for voice coils. As successful as these dark brown plastic films were for most hi-fi voice coils, they also had some less attractive properties, principally their cost, and an ...
Aluminized Kapton, with foil thickness of 50 and 125 μm, was used on the Apollo Lunar Module. [7] The polyimide gives the foils their distinctive amber-gold color. Space blankets are made by vacuum-depositing a very precise amount of pure aluminum vapor onto a very thin, durable film substrate. [8]
Polyimide (PI), a thermoplastic polymer of imide monomers, is proposed for film capacitors called Polyimide-, PI- or Kapton capacitors. [50] [54] Kapton is the trade name of polyimide from DuPont. This material is of interest because its high temperature resistance up to 400 °C.
The real-life story, which is in theaters now, follows Ohio attorney Rob Bilott (portrayed by Mark Ruffalo) as he steadfastly pursues a case against DuPont, the chemical company that created Teflon.
Arduengo's work with DuPont also involved a number of applied projects including the flexible polyimide film, Kapton-ZT, that is widely used in electronics for flexible printed circuits, connections, and insulation. [27]
