![]() ![]() Kapton® HN meets ASTM D-5213 (type 1, item A) requirements.ĭuPont ™ Kapton® MT polyimide film is a homogeneous film possessing 3x the thermal conductivity and cut through strength of standard Kapton® HN. Kapton® HN is the recommended choice for applications that require an all-polyimide film with an excellent balance of properties over a wide range of temperatures. HN film can be laminated, metallized, punched, formed or adhesive coated. Kapton® FPC meets IPC 4202/1 requirements.ĭuPont ™ Kapton® HN general-purpose film has been used successfully in applications at temperatures as low as -269☌ (-452☏) and as high as 400☌ (752☏). In applications where superior adhesion and low shrinkage are important, Kapton® FPC is the polyimide film of choice. Adhesion data for FPC can be referenced in the adhesion to Kapton® technical bulletin. Kapton® FPC offers superior dimensional stability and adhesion and is specifically designed for flex circuit manufacturers. Kapton® FN meets ASTM D-5213 (type 2, item A) requirements.ĭuPont™ Kapton® FPC polyimide film is treated on both sides and has the same excellent balance of physical, chemical and electrical properties over a wide temperature range offered by general purpose Kapton® HN. Kapton® FN is recommended in applications that require a heat bondable film, or moisture and chemical resistance beyond the capabilities of uncoated Kapton® films. Kapton® FN imparts heat sealability, provides a moisture barrier, and enhances chemical resistance. Kapton® film also has a history within the spacecraft industry and NASA programs-often serving as a key component to insulation systems designed to protect spacecraft on their re-entry into the Earth’s atmosphere.ĭuPont ™ Kapton® FN is a general purpose HN film that is coated or laminated on one or both sides with Teflon® FEP fluoropolymer. The film’s lightweight construction provides a desired advantage over other insulators relevant to the aircraft industry. Kapton® insulated electrical wiring has long be used in civil and military aircraft. The result is that the ABS part being printed will not separate from the build structure as it cools and shrinks (amending a common cause of print failure within the industry). The process is simple: Kapton® is laid down on a flat surface and ABS is extruded on to its surface. This relationship between materials has led to the widespread use of Kapton® as a build surface for 3D printing machines. Kapton® and ABS (acrylonitrile butadiene styrene) bond and adhere to each other very effectively. As an added bonus, it’s also fairly insensitive to radiation damage. The material’s advanced mechanical and thermal stability and high transmittance to X-rays make it an ideal material for X-ray technology. Kapton® is a popular material of choice for windows of all kinds at X-ray sources-synchrotron beam-lines, X-ray tubes, and X-ray detectors, to name a few. Its protection is available throughout the whole production process of electronic products and is often still present in the final consumer good. ![]() The film typically acts as an insulation and protection layer on electrostatic sensitive and fragile components. ![]() Kapton® film is used in a large variety of industries-listed below are a few of the most commonly related industries relevant to the material:ĭue to its electrical insulation ability and temperature stability, Kapton® has long served a useful purpose in electronic manufacturing. ![]()
