High-Quality Ceramic Fiber Blanket (1100℃-1600℃) - Lightweight Insulation For Industrial Furnaces & Thermal Protection

1. Product Overview

This Ceramic Fiber Blanket is manufactured via strict processes: first, high-purity bauxite and quartz are melted in electric furnaces (1700-1800℃) to form molten inorganic glass; then, high-pressure air is used to spin the melt into ultra-fine fibers (3-5 μm diameter); after that, the fibers are laid into a continuous cotton layer and reinforced via needle-punching (regular needle replacement ensures strong tensile strength); finally, heat treatment (200-300℃) removes moisture and stabilizes the structure. Unlike traditional insulation materials (e.g., rock wool, foam boards), it's a pure inorganic material-non-combustible (Class A fire rating), no formaldehyde release, and maintains stability at 1100℃-1600℃. The product covers 4 temperature grades (1100℃ ordinary, 1260℃ standard, 1400℃ high-temp, 1600℃ ultra-high-temp) and is supplied in standard rolls (width 610/1220mm, length 3600-7200mm, thickness 6-50mm) with 3 packaging options (single roll woven bag/carton, 2-roll woven bag) for secure transportation.

 

2. Key Features

Grade-Specific High-Temp Performance:

1100℃ grade: For low-temp equipment (e.g., drying ovens, household appliance insulation)

1260℃ grade: For ceramic/glass kiln backups (most widely used, cost-effective)

1400℃ grade: For steel annealing furnace linings (resists frequent thermal shocks)

1600℃ grade: For petrochemical cracking furnaces (ultra-high temp stability)

Ultra-Efficient Insulation: Thermal conductivity 0.03-0.12 W/m·K-50% lower than traditional refractory bricks, reducing industrial furnace heat loss by 25-30% and cutting fuel consumption by 18-22%.

Lightweight & Easy Installation: Density 64-160 kg/m³ (1/5-1/10 of dense refractory materials), single roll weight ≤80kg-lowering furnace structural load by 40%; good flexibility (can be bent/cut) allows quick fitting of irregular surfaces (e.g., furnace arches, pipeline elbows), installation efficiency 2x higher than bricks.

Stable & Durable: Reheating linear shrinkage ≤3% (1800℉/3h), Fe₂O₃ content ≤0.2% (anti-oxidation); withstands 1000℃-room temp thermal cycles ≥50 times without cracking, service life 3-5 years (2x longer than ordinary fiber blankets).

Multi-Scene Adaptability: Beyond industrial furnaces, it works for building fireproofing (wall/door gaps), automotive exhaust insulation, and aerospace test equipment-thanks to sound absorption (noise reduction ≥20dB) and chemical stability (resists most acids/alkalis except molten alkali).
