THERM-AL® H is a series of polyester coated closed weave glass fabrics with 180°C thermal capability, good flexibility and tear strength, and exceptionally high tensile strength.

Thermal aging tests conducted in accordance with both ASTM D902 (Volatility Index of Coated Woven Glass Cloth) and ASTM D1830 (Curved Electrode Test) have proven that Therm-Al H has a thermal endurance in excess of 50,000 hours at 180°C.

Available in standard format and Light Mica Dusted format. The Light Mica Dusting makes the material less sticky for ease of handling in certain applications.
