Product Description
Ceramic Fiber Blanket – Flexible, High-Temperature Insulation for Demanding Industrial Applications
Product Overview:
Our Ceramic Fiber Blanket is composed of long, flexible, interwoven fibers manufactured by the “blown” and “spun” process. It yields a strong, lightweight, and durable blanket designed for continuous service in a temperature range from 1100°C to 1430°C, depending on the grade. It combines the heat resistance of a hard refractory with a thermal insulation value five times better, making it an ideal solution for energy saving and thermal management.

Key Features:
- Low Thermal Conductivity: Excellent insulation properties reduce heat loss.
- Very Low Heat Storage: Enables rapid heating and cooling cycles.
- High Tensile Strength: Durable and resistant to tearing during handling and installation.
- Excellent Thermal Shock Resistance: Performs reliably under rapid temperature changes.
- No Binder, Safe: Contains no binders, producing no fumes or furnace atmosphere contamination. It is asbestos-free.
- Quick Installation & Repair: Requires no curing or dry-out time; can be fired to operating temperature immediately. Damaged linings can be cooled and repaired quickly.
Applications:
- Ceramic Industry: Kiln car insulation and seals, continuous and batch kilns.
- Steel Industry: Heat treating/annealing furnaces, furnace door linings, soaking pit covers, ladle covers, hot face repairs.
- Refining & Petrochemical: Reformer and pyrolysis lining, tube seals/gaskets, high-temperature pipe/duct insulation.
- General: Back-up insulation, expansion joints, and areas requiring sound absorption.
