The tape is manufactured from high-strength glass fiber cloth backing coated with heat-resistant silica gel or acrylic adhesive, delivering exceptional mechanical durability and high-temperature thermal insulation.
Both HY420-1 and HY420-2 models are rated for heat resistance up to 260°C, making them suitable for wave soldering, reflow ovens, and harsh thermal operating environments.
HY420-1 is a single-sided glass fabric tape with an adhesion to steel of 8 N/25mm, serving as an equivalent to 3M 69 and TESA 4618. HY420-2 is a double-sided version offering 6 N/25mm adhesion to steel for bonding and mounting purposes.
Both products provide a dielectric breakdown voltage resistance rating of 2.5 KV, ensuring safe electrical insulation across high-voltage motors, transformers, and battery systems.
Common applications include motor and transformer coil wrapping, lithium power battery core binding, EV electric motor insulation, PCB gold finger protection during SMT wave soldering, and internal wiring harness fixation in thermal appliances.
