| KAPTON® FILM (Click for Properties & Specs) Back to the Materials Group main page. Kapton® (polymide) Film is an exceptionally strong heat resistant film with an excellent combination of mechanical and electrical properties. Kapton® has been used successfully in various applications at temperatures from 269ºC to 400ºC. It is flame resistant, does not melt, resists effects of organic solvents and has a very high resistance to high-energy radiation. TYPE H An all-purpose uncoated film, with toughness and dielectric integrity at very high and very low temperatures. Other gauges and types of DuPont Kapton® are available upon special quotation. Yield Information 3" ID x 6" OD = 1 lb. per inch of width 3" ID x 9-1/2" OD = 3 lbs. per inch of width |
