Description: Polyimide tape, also known as PI tape (or Kapton tape), is a special type of tape with a polyimide film base coated with a high-temperature resistant adhesive. Colors include black, yellow, white, blue, transparent, red, and green.
Its core performance primarily comes from its base material—the polyimide film. Polyimide is a high-performance engineering plastic with excellent insulation, high-temperature resistance, low-temperature resistance, chemical corrosion resistance, and good mechanical properties.
Features:
High-Temperature Resistance: (Polyimide tape) remains stable in high-temperature environments, with a maximum operating temperature exceeding 260°C.
This makes it particularly suitable for applications such as engine components, furnace seals, and aerospace engine heat shields under high-temperature working conditions.
Chemical Corrosion Resistance: This tape exhibits strong resistance to a variety of chemicals, including acids, alkalis, solvents, and oxidizers.
Therefore, it has wide applications in the chemical industry, such as anti-corrosion coatings, sealing rings, and pipe linings. Electrical Insulation Properties: The tape possesses excellent electrical insulation properties, with a low dielectric constant and a small loss tangent, making it highly valuable in electronic equipment and communications.
For example, it can be used to manufacture high-frequency cable insulation layers, microwave device encapsulation, and insulation materials for high-voltage direct current transmission lines. High Mechanical Strength: This tape exhibits high tensile strength, impact resistance, and abrasion resistance, maintaining stable performance even in harsh working environments.
This makes it suitable for manufacturing high-strength structural components, bearings, and gears. Good Biocompatibility: Polyimide tape (PI tape, also known as Kapton tape) does not contain substances harmful to the human body, thus possessing potential applications in the medical field, such as in the manufacture of artificial joints.
Application Scenarios:
- Electronic Circuit Board Manufacturing: Wave soldering shielding and gold finger protection: During the electronic circuit board manufacturing process, polyimide tape can effectively protect sensitive components such as gold fingers from damage caused by solder splatter.
- Motor and Transformer Manufacturing: Used for insulating and wrapping motor and transformer coils, as well as wrapping and securing the ends of high-temperature coils. 3. Temperature measurement, thermal resistance protection, capacitors, and wire winding, etc.
- Aerospace and Automotive Manufacturing: Used for fixing, sealing, and stitching, providing reliable mechanical support and protection. Suitable for harsh environments such as high temperature, high humidity, and strong corrosion, for example, engine parts, furnace seals, and aerospace engine thermal pads.
- Power and Energy Industry: Used for insulation protection of insulated cables, motor coils, transformers, and other electrical equipment. In SMT processes, polyimide tape can be used to attach thermocouple wires to measure furnace temperature. Also used for insulation and high-temperature protection on top of polymer batteries.
- Chemical and Pharmaceutical Industry:
- Used for packaging, sealing, and fixing, providing reliable chemical protection.
- Resistant to corrosion from acids, alkalis, solvents, and other chemicals without causing corrosion or discoloration.
- Special Applications: It can be die-cut and processed into any other shape and used for some special applications, such as picking up material from connector placement machines to replace traditional sheet metal. It is also used to protect surrounding components (protecting unsoldered chips) when soldering various precision integrated circuits.
