Glass fiber tape is a kind of high-performance industrial tape based on high-strength glass fiber cloth and coated with high-temperature resistant silica gel or acrylic adhesive. It has excellent heat resistance, insulation, tensile strength and chemical resistance, so it is widely used in the fields of electronics, electricity, new energy and industrial manufacturing.
Glass fiber adhesive tape is soft, easy to stretch and good to fit, which is very suitable for bundling, branch fixing and temporary fixing of wire harness.
- Arranging and fixing the internal wiring harness of household appliances
- Automotive wiring harness bundling and branch fixing
- Internal connecting wires of electronic equipment
Due to the light and thin material, fiberglass tape is suitable for insulation scenes sensitive to thickness, such as:
- Lightweight insulation of small motor coils
- Auxiliary insulation of inductors and transformers
- Insulation winding of electronic components
In the manufacture of lithium batteries, glass fiber tape is often used for:
- Light packing on the surface of battery core
- Temporary fixation between battery core and protective plate
- Bundling and insulation of wire harness inside module
⚡ Its thin and light characteristics will not increase the extra thickness of the battery cell, and it is suitable for designs with high space requirements.
Glass fiber tape can be used in SMT and PCB processes:
- Temporary fixing of flexible circuit board (FPC)
- Masking areas that do not need to be tinned or sprayed
- Temporary protection in manufacturing process
Frequently Asked Questions
Q
What is the maximum heat resistance temperature of fiberglass tape?
The heat resistance range of our fiberglass tape varies by model. Most models (HY430-1 to HY430-4) are rated for -20℃ to 80℃, while HY430-5 is rated for -10℃ to 80℃ and HY430-6 for -5℃ to 70℃. Please refer to the specification table above to select the appropriate model for your application.
Q
What is the difference between non-residual and residual glass fiber tape?
Non-residual glass fiber tape (HY430-5) leaves no adhesive residue after removal, making it ideal for applications where clean removal is required. Residual glass fiber tape (HY430-6) may leave slight adhesive traces upon removal and is typically used where permanent or semi-permanent bonding is acceptable.
Q
Is fiberglass tape suitable for use in lithium battery manufacturing?
Yes. Fiberglass tape is widely used in lithium battery manufacturing for surface wrapping of battery cores, temporary fixation between the battery core and protective plate, and internal wire harness bundling. Its thin profile ensures no unnecessary increase in cell thickness, which is critical for space-sensitive battery designs.
Q
Can fiberglass tape be used for PCB and SMT processes?
Absolutely. Fiberglass tape is commonly applied in SMT and PCB manufacturing for temporarily fixing flexible circuit boards (FPC), masking areas that should not be tinned or coated, and providing temporary protection during various stages of the manufacturing process.
Q
Which fiberglass tape model is equivalent to 3M898?
Model HY430-1, which features a standard fiberglass carrier with a thickness of 0.17mm and a tensile strength of 800N, is the equivalent to 3M898. It offers comparable performance for wire harness bundling and industrial insulation applications.
Q
What makes fiberglass tape suitable for insulation winding in electronics?
Fiberglass tape features a thin and lightweight construction — with thicknesses starting from just 0.14mm — combined with excellent electrical insulation properties. This makes it ideal for insulation winding of small motor coils, inductors, transformers, and other electronic components where minimal added thickness is critical.
