Ceramic Fiber Blanket

Product Overview

Ceramic Fiber Blanket is manufactured through a high-temperature melt-spinning or blown-fiber process with double-sided needling technology. The product is white in color with uniform dimensions, and integrates fire resistance, thermal insulation, and heat preservation in a single material.

It contains no binders and maintains good flexibility and tensile strength under neutral and oxidizing atmospheres.

Key Features

Low Thermal Conductivity

Excellent insulation, with conductivity as low as 0.086 W/m·K at 400°C.

Lightweight Design

Low bulk density (96–128 kg/m³) reduces structural load and simplifies installation.

High-Temperature Stability

Maintains performance integrity at temperatures up to 1600°C for extended periods.

Chemical Resistance

Resistant to most corrosive chemicals, except hydrofluoric and phosphoric acid.

Good Tensile Strength

Compressive strength 0.08–0.12 MPa for durability during handling and installation.

Easy Installation

Flexible material that can be cut, wrapped, and installed on complex surfaces.

Technical Specifications

Available in six grades to meet various temperature and application requirements. All products undergo strict quality control and testing for consistent performance.

Applications

Industrial Furnaces & Kilns

Backup insulation and lining for furnaces, ceramic kilns, and heat treatment equipment.

High-Temperature Pipelines

Thermal insulation wrapping for high-temperature pipes, ducts, and heat exchangers.

Thermal Equipment

Heat preservation for boilers, heaters, and thermal processing equipment.

Expansion Joint Sealing

Filling and sealing for furnace body expansion joints, doors, and covers.

Fire Protection

Fire barrier and thermal insulation in building construction and industrial facilities.

Backing Materials

Backup insulation layer behind refractory bricks and castables in furnace construction.

Installation Method

Surface Preparation

Ensure the substrate surface is clean, dry, and free from oil, dust, and loose materials.

Cutting & Sizing

Cut the blanket to required dimensions with a sharp knife or scissors. Allow 5–10% extra for compression.

Anchoring System

Install ceramic fiber anchors at recommended spacing (typically 300 mm centers) for secure attachment.

Layer Installation

Install blanket layers with staggered joints. Ensure tight butting between adjacent pieces without gaps.

Sealing & Finishing

Apply ceramic fiber coating or facing material if required for hot-face protection.
