Heat resistant tape is an indispensable material in industrial production. It is widely used in many industries due to its excellent heat resistance and multiple functions. This article will detail the types, characteristics, and applications of heat-resistant tape in different fields.
What is heat resistant tape?
In fact, “heat resistant” is not an absolute condition, but a relative term. Most heavy-duty tapes can withstand operating temperatures up to 250°F (120°C), but once the temperature reaches 250°F or higher, special high-temperature resistant tapes are required.
Adhesive of heat resistant tape
Generally speaking, when we talk about temperature-resistant tapes, the most commonly used adhesive is silicone, which can withstand temperatures from -60°F to 500°F (-51°C to 260°C), at least in the short term. This is useful for applications that do not require long-term high-temperature resistance. Silicone adhesives are commonly used in high-temperature aerospace, automotive, and electrical applications. The silicone is used in PET tape/glass cloth tape/Teflon tape/polyimide tape etc. Below are details.
Types
PET high-temperature tape: polyester film is the base material, coated with silicone. PET high-temperature tape usually has a temperature resistance of 356°F-392°F（180-200℃） and is suitable for electronic manufacturing, high-temperature coating masking, etc.
Teflon glass cloth high-temperature tape(PTFE glass cloth tape): It is made of glass fiber cloth coated with Teflon emulsion as the base material and then coated with silicone. Teflon high temperature tape is not only resistant to high temperatures (long-term use temperature resistance up to 260°C) but also has the characteristics of low friction, wear resistance, and moisture resistance. It is widely used in the wire and cable industry and the food processing industry.
PI (polyimide) heat resistant tape (Kapton tape): with polyimide film as the base material and coated with high temperature silicone. This tape has extremely high temperature resistance, with a long-term temperature resistance of up to 260°C, and is suitable for more severe high temperature environments, such as transformer coil insulation bundling and mobile phone lithium battery manufacturing.
Glass cloth tape: is a special tape made of glass cloth as the base material and coated with high-performance silicone. It has excellent high temperature resistance, insulation, tensile strength, and corrosion resistance, and is widely used in various industrial occasions.
Application of heat-resistant tape
Electronic industry: High-temperature tape is mainly used in the electronic industry for the production of printed circuit boards, the fixing and shielding of electronic components. For example, PI high-temperature tape is often used to protect gold fingers during reflow soldering to prevent solder overflow and other contamination.
Automotive industry: In the automobile manufacturing process, high-temperature tape is used for coating shielding, heat insulation, and insulation sheathing of wires and cables. PET high temperature tape is often used for paint protection of automotive parts due to its good high temperature resistance and shielding properties.
Food and pharmaceutical industry: Teflon tape is used in the food and pharmaceutical industry for the surface sheathing of conveyor belts and processing equipment due to its corrosion resistance and moisture resistance to ensure hygiene and safety during the production process.
How to storage
Although heat resistant tape has excellent performance, the following points should still be noted during storage and use:
When storing, avoid sunlight, rain, and high-temperature environments, keep it clean and dry.
Different types and specifications of high-temperature tapes should not be mixed to avoid affecting the use effect.
During loading, unloading, and transportation, avoid severe vibration and extrusion to prevent damage to the tape.
Other adhesion
Acrylic glue can also withstand high temperatures, but not as well as silicone. Such as acrylic foam tape/aluminum foil tape also can resist high temperatures.
Conclusion
In short, heat resistant tape plays an important role in industrial production with its high temperature resistance, wear resistance, and insulation properties. Correct selection and use of heat resistant tape can not only improve production efficiency but also ensure production safety and product quality. With the advancement of science and technology, the types and application areas of heat resistant tape will continue to expand to provide support for more industries.
