Polyimide film as carrier, coated with acrylic adhesive, specially used for insulation and protection of aluminum and steel surface in lithium/nickel/cadmium batteries. Polyimide (sometimes abbreviated PI) is a polymer of imide monomers. Polyimides have been in mass production since 1955. With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, e.g. high temperature fuel cells, displays, and various military roles. Polyimide films shows excellent electrical insulation properties, high temperature resistant, and excellent solvent resistant. Due to its large range of temperature stability, and its electrical isolation ability, polyimide tape is usually used in electronic manufacturing as an insulation and protection layer on electrostatic sensitive and fragile components. Polyimide Tape 7412P with polyimide film and acrylic adhesive used for PCB solder masking and other high temperature applications. Electrolyte is a chemical compound that conducts electricity by changing into ions when melted or dissolved into a solution. Polyimide tapes start with a LINQTAPE polyimide film base and then an adhesive layer is applied to it. The base material itself has the same high temperature resistance, and dielectric properties described above, but the adhesive type and properties plays an important role in the selection process of a polyimide tape. For high temperature applications, silicone is the adhesive of choice for polyimide tapes because it has the highest temperature resistance and maintains its adhesion the most when exposed to higher temperatures. In applications where silicone can absolutely not be used, or in applications that require a higher room-temperature adhesion is needed, offers an acrylic adhesive version of polyimide tape.
