? Frequently Asked Questions
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 silica gel or acrylic adhesive. This combination delivers excellent heat resistance, electrical insulation, and mechanical strength.
What is the maximum heat resistance temperature of this tape?
Both the HY420-1 and HY420-2 models offer a heat resistance of up to 260°C, making them suitable for demanding high-temperature industrial and electronic applications.
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 glass fabric tape with an adhesion of 6 N/25mm. Both share the same film thickness (0.1mm), total thickness (0.19mm), tensile strength (380 kg/25mm), heat resistance (260°C), and voltage resistance (2.5KV).
Which industries commonly use glass cloth adhesive tape?
Glass cloth adhesive tape is widely used across multiple industries including electronics manufacturing (SMT, PCB, FPC), new energy and lithium battery production, electric motors and transformers, household appliances, and industrial mechanical equipment requiring high-temperature insulation and fixation.
Is this tape equivalent to 3M or TESA products?
Yes. The HY420-1 glass fabric tape is a direct equivalent to 3M69 and TESA4618, offering comparable performance in terms of heat resistance, voltage resistance, and adhesion properties at a competitive value.
