Lanmar Glass Cloth Tapes (non-PTFE) are engineered for high-temperature performance, electrical insulation, and industrial durability across demanding applications. These fiberglass cloth tapes offer excellent heat resistance, cut-through strength, abrasion resistance, and flexibility, making them ideal for cables, motors, transformers, and general electrical insulation uses.

For surface protection in thermal processes, Lanmar’s double-faced glass cloth tapes are widely used in plasma spray masking, HVOF, and grit blast applications. Item #775-8R Plasma Spray Masking Tape features a silicone rubber coating that provides high heat resistance and a tacky surface, allowing it to also function as a friction tape for roller wrap and drive wheel applications.

For applications requiring heat reflectivity and thermal shielding, #725-7 aluminum foil fiberglass tape combines fiberglass strength with reflective aluminum foil, making it ideal for insulation systems, electrical protection, and heat management environments.
