Frequently Asked Questions
Q What is glass cloth adhesive tape made of?
Glass cloth adhesive tape is made from high-strength glass fiber cloth as the base material, coated with either high-temperature resistant silicone adhesive or acrylic adhesive. This combination delivers outstanding heat resistance, electrical insulation, and mechanical durability.
Q What is the maximum heat resistance temperature of HY420 glass fabric tape?
Both HY420-1 (single-sided) and HY420-2 (double-sided) glass fabric tapes offer a heat resistance of up to 260°C, making them suitable for demanding high-temperature industrial and electronic applications.
Q What is the difference between HY420-1 and HY420-2?
HY420-1 is a single-sided glass fabric tape with an adhesion to steel of 8 N/25mm, while HY420-2 is a double-sided version with an adhesion of 6 N/25mm. Both share the same film thickness (0.1 mm), total thickness (0.19 mm), tensile strength (380 kg/25mm), heat resistance (260°C), and voltage resistance (2.5 KV).
Q Is glass fabric tape suitable for use in lithium battery and new energy applications?
Yes. Glass fabric tape is widely used in the lithium battery and new energy sector for binding and insulating power battery cores, protecting high-temperature wiring harnesses in battery modules, and providing insulation for motors and electronic control systems in new energy vehicles.
Q Can glass cloth tape be used in SMT and PCB manufacturing processes?
Absolutely. Glass cloth adhesive tape is commonly used in SMT processes for gold finger shielding during PCB tin furnace operations, high-temperature masking during wave soldering and reflow soldering, FPC flexible circuit board reinforcement, and general high-temperature protection of electronic components.
Q Which well-known tape products is HY420 equivalent to?
The HY420-1 single-sided glass fabric tape is equivalent to 3M 69 and TESA 4618, which are industry-standard high-temperature glass cloth tapes widely recognized for their performance in electrical insulation and thermal resistance applications.
