The adhesive coated polyimide film double-sided tape has excellent insulation, wear resistance, acid and alkali resistance, high temperature resistance of 300 degrees/10 minutes, and long-term use at 180 degrees. Many applications are used for welding prevention maintenance, high temperature insulation binding of transformer coils; Capacitor insulation raw materials, PCB board gold finger high-temperature spraying cover maintenance, mobile phone lithium battery production bundling.
Polyimide double-sided tape, also known as KAPTON double-sided tape, is based on 0.025mm polyimide film and coated with imported organic silica gel on both sides, with a total thickness of 0.1mm. It can be used to composite PET fluoroplastic release film on one or both sides. It can be used as advanced electronic insulation materials and as an auxiliary fixture in various high-temperature environments, such as soft circuit board production and high-temperature bonding of electronic components; The utility model is also particularly suitable for fixing the flexible circuit board patch with the manufacturing tool when it passes reflow soldering soldering.
Polyimide is an engineering plastic with the same temperature resistance grade, which can be used at 430 ℃ for a long time. It has excellent scale stability, heat insulation, oxidation stability, chemical resistance and good machining function. Generally speaking, polyimide can be used to replace traditional plastics as long as it is high temperature resistant and chemical resistant. Now polyimide is mainly used in aerospace, aviation, ships, electronics, precision machinery and office machinery.
In conclusion, the main uses of polyimide tape are as follows:
In the electronics and electrician profession, it can be used for insulation wrapping of H-class motors and transformers with high requirements, fixing the end of high-temperature resistant coils, maintaining temperature measuring thermal resistance, capacitance and wire entanglement, and other bonding insulation under high-temperature working conditions. In the field of circuit board manufacturing, it can be used for electronic maintenance and posting, especially suitable for various electronic components that require high-temperature and moisture-proof maintenance such as SMT temperature resistance maintenance, electronic switches, PCB board gold finger maintenance, electronic transformers, relays, etc.
