Features and Uses of High Temperature Insulating Tape
September 08,2022
High temperature insulating tape is a special tape composed of base tape and pressure-sensitive adhesive layer, because it not only has good high temperature resistance, but also exhibits excellent insulation.
Such performance has a lot to do with the materials used. The base tapes of high-temperature insulating tapes are generally cotton cloth, synthetic fiber fabrics, and plastic films, while the adhesive layer is made of rubber and tackifying resins.
There are two main production processes for high-temperature insulating tape, namely the rubbing method and the gluing method. No matter which process is used, the products made can be widely used for wrapping and jointing wires used below 380V. , insulation sealing, and other electrical work.
High temperature insulating tape can play the role of preventing leakage and insulating protection in electrical construction by its good insulation voltage resistance, flame resistance, weather resistance and other characteristics. It can not only be used for insulating cladding in the wire and cable industry; it can also play a role in the insulating lining of the electrical oxygen industry.
Features of high temperature insulating tape:
- Good thermal stability, can work at 200℃ for a long time, and can withstand high temperature of 260℃ in a short time.
- Soft and tear-resistant, with strong adhesive force, not easy to deform, suitable for pasting and protecting the surface of various profiles.
- No glue residue, no glue residue will be left when the tape is torn off after a long time of high temperature curing.
- Non-adhesion of high temperature tape: smooth surface, not easy to adhere to any substance. It is easy to clean all kinds of oil stains, stains or other attachments attached to its surface; almost all adhesive substances such as paste, resin and paint can be easily removed;
- High temperature tape is used for low temperature -196 ℃ and high temperature between 300 ℃, with weather resistance and anti-aging. After practical application, if placed for 200 days at a high temperature of 250°C, not only the strength will not decrease, but also the weight will not decrease; if placed at a high temperature of 350°C for 120 hours, the weight will only decrease by about 0.6%; at -180 ℃ ultra-low temperature and can maintain the original softness.
Application of high temperature resistant insulating tape:
In the electronic and electrical industry, it can be used for high-requirement H-class motor and transformer coil insulation wrapping, high temperature resistant coil end wrapping and fixing, temperature measurement thermal resistance protection, capacitor and wire entanglement and other bonding insulation under high temperature working conditions.
High temperature resistant insulating tape is especially suitable for SMT temperature resistant protection, electronic switches, PCB gold finger protection, electronic transformers, relays and other electronic components that require high temperature resistance and moisture-proof protection. High temperature resistant insulating tape has good dimensional stability at high temperature, low thermal shrinkage, and maintains good flatness when heated.
