Fiberglass Insulation Tape
Alkali-free woven fiberglass insulation tape for thermal insulation, electrical insulation, and high-temperature wrapping. Adhesive-free fiberglass tape with high tensile strength, low thermal conductivity, and up to 550°C continuous rating. Ideal for pipe wrap, cable insulation, and heat shielding. Custom widths and lengths. ISO & SGS certified.

Adhesive-Free Thermal & Electrical Insulation
Woven alkali-free fiberglass tape for applications where adhesive tapes fall short — high-temperature wrapping, electrical insulation, and flame protection. No adhesive residue, no outgassing, no cold-flow.
Up to 550°C Continuous
Alkali-free E-glass woven tape rated for continuous high-temperature insulation.
Electrical Insulation
Inherent dielectric strength for transformer, motor, and cable wrapping.
Fully Customizable
Width 6-150mm, length 10-100m, core 14-83mm — built to your spec.
Export Packaging
Individual roll wrapping, labeled cartons, palletized for container.
