Glass Cloth Tape - High temperature resistant tape 500℃

Glass cloth is an inorganic material that is non-combustible and has excellent high-temperature resistance. Glass fiber cloth itself can be used at temperatures above 500°C. It also has a high tensile strength, which is over 5 times higher than that of a 25μm PET film. In addition, glass cloth has excellent chemical resistance and flexibility. Due to these properties, glass fiber woven cloth is commonly used as a substrate for tapes.

Glass Cloth Tape

Since glass fiber cloth has good high-temperature resistance, it is often used to make high-temperature resistant tapes, which are usually coated with thermosetting natural rubber or acrylic-based pressure-sensitive adhesives. However, the heat resistance of these two types of adhesives is relatively low, with the heat resistance level of natural rubber being around 130°C and acrylic-based pressure-sensitive adhesive being below 155°C. If coated with silicone-based pressure-sensitive adhesive, the temperature resistance of the tape can reach over 180°C. Silicone glass cloth tapes have good flame retardancy and can meet the requirements of the UL-510 standard with some treatment. Further cross-linking can reduce the contamination of uncross-linked silicone on the substrate.

You-San Technology’ glass cloth tapes are made with high-performance glass cloth as the base material and coated with silicone adhesive. They are primarily used for:

1.Insulation, bundling, and long-term protection of coils, motors, and transformers.

2.Heavy-load, high-temperature equipment or air conditioner contacts.

3.Surface protection in powder coating.

4.Repairs and reinforcement of insulation in mining equipment.

5.Fixing non-sticky high-temperature insulators.
