Key Characteristics

Extreme Temperature Resistance: Continuous service up to 800–815°C (1470–1500°F), short‑term peak to 1000–1095°C (1830–2000°F).
Excellent Thermal Insulation: Low thermal conductivity, forms an effective heat barrier.
Superior Fire & Flame Resistance: Non‑combustible, resists direct flame and prevents fire spread.
Abrasion & Mechanical Durability: Coating reinforces surface, reduces wear, tearing, and fiber shedding.
Molten Metal Splash Protection: Defends against molten aluminum, zinc, steel, and welding sparks/slag.
Chemical Stability: Resists acids, alkalis, ozone, UV, and weathering; low moisture absorption.
Good Flexibility & Fabricability: Remains pliable for cutting, sewing, wrapping, and custom shaping.
Electrical Insulation: Inherits good dielectric properties from fiberglass.
Long Service Life: Reduced maintenance and replacement frequency in harsh environments.
