Also called Kapton tape, this polyimide adhesive tape boasts exceptional heat resistance and electrical insulation. It stays stable under extreme high temperatures like welding and reflow soldering, preventing leakage and short circuits for electronic components. With great tensile strength, wear and chemical resistance, it adheres firmly and leaves no residue after peeling. Custom specifications and complete certifications are provided. It is an essential insulating material widely applied in electronics, new energy and electrical equipment industries.
Polyimide adhesive tape, also known as Kapton tape, is renowned for its outstanding high-temperature resistance and superior electrical insulation performance, and it is widely used in electronic assembly, electrical equipment, new energy batteries and precision circuit processing fields. Taking high-performance polyimide film as the base material and compounded with high-temperature resistant adhesive, this tape is designed for professional heat-resistant insulation work, and it can keep stable physical and chemical properties in extreme high-temperature environments.
High temperature and electric leakage are common hidden dangers in the operation of electronic components and circuits. Conventional insulating materials will age, soften or lose insulation capacity when exposed to high temperature for a long time. Polyimide adhesive tape breaks through the performance limitations of ordinary tapes. It can resist instantaneous and long-term high temperature exposure, and will not melt, deform or lose adhesion in high-temperature working environments such as welding, reflow soldering and equipment operation. Its excellent electrical insulation can effectively isolate circuits, prevent short circuits, electric leakage and electromagnetic interference, and fully protect the safe operation of precision electronic parts.
In terms of material performance, polyimide base film has ultra-high tensile strength, wear resistance and chemical resistance, and is not easy to be damaged by chemical solvents and mechanical friction in the production environment. The matched adhesive layer features strong adhesion and low residue. When used for winding, wrapping and surface insulation of circuit boards, motor coils, battery components and other products, it fits tightly without falling off. After disassembly, there is no residual glue on the component surface, which will not affect the subsequent use and secondary processing of products.
This series of adhesive tapes supports diversified size customization, including standard finished rolls and large master rolls, to meet the procurement needs of different manufacturers. All products strictly follow industrial production standards and have complete qualification certificates. From precision electronic processing to new energy equipment manufacturing, polyimide adhesive tape has become an indispensable heat-resistant and insulating material. It provides long-term and reliable protection for industrial production with stable quality, helping customers improve product qualification rate and product safety performance.
