Ceramic Fiber Boards | 1400°C – 1900°C
Ceramic Fiber Boards | 1400°C – 1900°C
Product Overview
Our ceramic fiber boards are high-performance thermal insulation materials designed for industrial furnaces and kilns. Available in classification temperatures from 1400°C to 1900°C, they offer low thermal conductivity, low heat storage, and stable performance under steady high-temperature conditions.
Key Features
- Low thermal conductivity – Reduces furnace energy consumption by 15–30%
- Low heat storage – Faster heating and cooling cycles, increases productivity
- Uniform fiber distribution – Consistent insulation performance
- Chemical stability – Resistant to most furnace atmospheres
- Precise dimensions – Easy installation, minimal on-site cutting
