Premium High-Temperature Glass Cloth Tape GL20S
GL20S is a heavy-duty, industrial-grade glass cloth tape engineered for extreme temperature environments and high-demand electrical insulation. Featuring a robust white glass fiber backing and a high-performance silicone adhesive system, it provides exceptional mechanical strength, thermal stability, and reliable adhesion.

This tape utilizes a specialized 0.130mm woven glass fiber cloth backing coated with a premium pressure-sensitive silicone adhesive, resulting in a total thickness of 0.180mm. Built to endure the most rigorous conditions, it boasts an impressive tensile strength of ≥300 N/25mm and a dielectric withstand voltage of 4 KV. Designed specifically for extreme heat operations, GL20S effortlessly withstands continuous exposure to 260°C for up to 30 minutes while guaranteeing a clean, residue-free removal. It is the ultimate solution for heavy-duty bundling, high-temperature masking, and critical electrical insulation.
