Polyimide (PI, Kapton-H®) films are widely utilized in the spacecraft industry for their insulating properties, mechanical durability, light weight, and chemical resistance to radiation. Electrical-Grade Kapton® Polyimide Film. Type HN film can be laminated, metallized, punched, formed, or adhesive coated. Table 2 provides a summary of the thermal stability and dielectric properties for a range of commercial PIs. (3674-CB) Probe Card - Probe Test (3825-PC) Processed Foods (2096-PF). General Kapton® information: Kapton® is. 025 mm, L 2 m, grade kapton hn; Synonyms: IM301200; find -GF47821495 MSDS, related peer-reviewed papers, technical documents, similar. Still PI materials remain exposed to a combination of high-energy electrons, protons, and ultraviolet (UV) photons, particles primarily responsible for. 05 and 0. Spin-coated polyamic acid (PAA) was baked at 80 °C for 30 min to remove the solvent, then cured in two steps under inert conditions: first at 260. Polyimide (also known as PI or Kapton) plays an important role in aerospace and microelectronics due to its attractive dielectric properties, mechanical strength, excellent thermal stability, and chemical properties [1–5]. 100 Pieces (MOQ). FTIR spectra of pure PI, TiO 2 -MWCNT-A/PI, and TiO 2 -MWCNT-B/PI composite structures are given in Fig. Polyimide (PI, Kapton-H®) films are widely utilized in the spacecraft industry for their insulating properties, mechanical durability, light weight, and chemical resistance to radiation. Kapton Film (KAPTON FILMS) polyimide PI Kapton film and Kapton tape is manufactured by DuPont, and is available through the Professional Plastics website. 3 % and 5. In membrane technology, polyimide (PI) membranes have been used for a long time already and in a wide variety of applications [1]. 50. Ultraviolet (UV) photooxidation has recently been developed to fabricate superhydrophobic polyimide (PI) films in combination with. High heat resistance. 075mm and 0. Polyimide films are usually thermosetting polymers synthesized by polymerizing an aromatic dianhydride and an aromatic diamine. Laminated to this is a 0. 8 / kg. Kapton ® Type FN, a Type HN film coated on one or both sides with Teflon ® fluorinated ethylene propylene (FEP) fluoropolymer resin, imparts heat sealability.

Known for excellent thermal stability, polyimides (PI) perform well under elevated temperatures. Processing Kapton ® Using Digital Laser Material Processing (DLMP ®) Technology. Kapton® polyimide film has a repeating structure of C22H10OsN2 and is synthesized by polymerizing an aromatic dianhydride and an aromatic diamine.
