1. Product Overview
The 1600 °C high-temperature resistant polycrystalline ceramic fiber blanket is a premium refractory insulation material made from high-purity alumina via high-temperature melting, fiber spinning, and crystallization processes. It exhibits exceptional thermal stability, corrosion resistance, and thermal shock durability. Designed for continuous use up to 1600 °C and capable of enduring short-term higher temperatures, it is an upgrade over standard ceramic fiber products.
Its uniform fiber structure and superior physicochemical properties make it ideal for demanding applications in metallurgy, petrochemical, power generation, aerospace, defense, and high-temperature heat treatment, offering superior insulation, fire protection, and thermal performance.
