In the fields of electronics manufacturing, aerospace, and high-temperature industries, heat-resistant tapes have become indispensable materials. Faced with high-temperature environments, chemical corrosion, and electrical insulation requirements, different types of heat-resistant tapes each have their unique advantages.
This article will provide an in-depth analysis of four main types of heat-resistant tapes: Kapton tape (polyimide tape), polyester tape, glass cloth tape, and FEP tape (F46), helping you fully understand their characteristics, application scenarios, and selection strategies.
Kapton tape (polyimide tape) is a high-end heat-resistant tape made using polyimide film as the base material and coated with high-performance organic silicone pressure-sensitive adhesive. It offers exceptional temperature resistance and excellent electrical insulation properties.
Polyester tape uses polyester film as the base material coated with pressure-sensitive adhesive. Although its temperature resistance is not as good as polyimide tape, itscost-effectivenessandgood overall performancemake it an ideal choice for many applications.

Glass cloth tape usesglass fiber woven base clothcoated with special coatings (such as polytetrafluoroethylene). It combines themechanical strength of glass fiberwith thechemical stability of high-temperature resistant coatings, making it an ideal choice for heavy industrial fields.
The FH film is a heat sealable film which is made by Polyimide film with one side or double side FEP coated. When combined with FEP resin, the Polyimide film remains excellent heat and electrical properties. This kind of film is widely used in high temperature wire manufacturing. When treated in a high temperature, the film will adhere from one side to another and from film to copper. The well sealed conditions enable the wire to be used in severe environment such as high temperature. under water and oil.

How to Choose the Right Heat-Resistant Tape
Consider these factors when selecting heat-resistant tape:
Temperature requirements: Determine thenormal operating temperature and peak temperatureof the application environment, choosing products with safety margins.
Chemical environment: Consider thetypes of chemicals(acids, alkalis, solvents, etc.) that will be contacted, selecting tapes with appropriate resistance.
Electrical needs: Choose products with sufficient dielectric strength based onworking voltage and insulation requirements.
Mechanical stress: Evaluatewear, tear, and tensile stressin the application, selecting tapes with appropriate mechanical strength.
Budget constraints: Find the balance betweenperformance requirements and budget, selecting the most cost-effective solution.
