Industrial Ceramic Fiber Bulk

1.Product Overview

Ceramic fiber bulk is a high-performance fire-resistant insulation material with alumina (Al₂O₃) and silicon dioxide (SiO₂) as the main components. It is made into fiber bulk by high-temperature melting and spinning or blowing. Its unique structure gives it excellent high temperature resistance, low thermal conductivity, light weight and chemical stability, and is widely used in industrial insulation, fire protection and thermal insulation.

3. Core Features

(1) High temperature resistance

Long-term use temperature range: 600℃~1430℃ (depending on the model), short-term tolerance to higher extreme temperatures, far exceeding traditional insulation materials.

(2) Ultra-low thermal conductivity

The thermal conductivity is as low as 0.03~0.15 W/(m·K) (normal temperature), effectively blocking heat transfer and achieving significant energy-saving effects.

(3) Lightweight and soft

The density is only 128~320 kg/m³, which reduces the load on equipment, is easy to cut and wind, and can adapt to complex shapes.

(4) Chemical inertness

Acid and alkali corrosion resistance, strong thermal shock resistance, stable performance in oxidizing or reducing atmospheres, and long service life.

(5) Environmental protection and safety

No asbestos components, no harmful gas release at high temperatures (some zirconium/chromium containing models need to pay attention to specific environments).

4.Typical application scenarios

Metallurgy: thermal insulation lining of furnaces, ladles, and heat treatment equipment.

Petrochemical: cracking furnaces, reactors, and high-temperature pipe insulation.

Electricity: gas turbines, boilers, and flue seals.

Aerospace: engine insulation, spacecraft thermal protection.

Fire protection: fire doors and escape passage flame retardant filling.

Construction: fire isolation belts of high-rise buildings, walls of industrial kilns.

Electronics: battery pack insulation, high-temperature sensor protection.

5.Advantages comparison (vs traditional materials)

6. Precautions for use

Safety protection: Wear goggles and masks during construction to avoid fiber dust contact with skin or inhalation.

Temperature limit: It is strictly forbidden to use over-temperature to prevent fiber crystallization and embrittlement.

Environmental adaptation: Chromium-containing products must avoid strong acid environments, and zirconium-containing products are not suitable for phosphate erosion scenarios.

Storage conditions: Dry and ventilated, moisture-proof and pressure-proof, to avoid stratification and hardening.
