In industries such as metallurgy, ceramics, power generation, and petrochemicals, high-temperature insulation materials are critical for maintaining operational efficiency and safety. Among these, bur glass fiber felt has emerged as a versatile and reliable material, widely used for thermal insulation, sealing, and fireproofing. Jiuqiang, a leading manufacturer, has been providing premium quality bur glass fiber felt solutions to meet global industrial demands.

This blog will explore the properties, applications, advantages, and industry insights of bur glass fiber felt, helping buyers and engineers make informed purchasing decisions.

1. What is Bur Glass Fiber Felt?

Bur glass fiber felt is a non-woven insulation material composed of fine glass fibers that are needle-punched or mechanically bonded to form a resilient mat. Its unique fiber structure provides excellent thermal resistance, low heat conductivity, and high mechanical strength.

Key Features:

• High-temperature resistance up to 550°C

• Lightweight yet durable structure

• Low thermal conductivity for superior insulation

• Flexibility and compressibility for easy installation

• Chemical resistance to most acids, alkalis, and solvents

The Jiuqiang brand ensures that every roll of bur glass fiber felt meets stringent quality standards and performance requirements.

2. Working Principle and Manufacturing Process

The performance of bur glass fiber felt largely depends on its manufacturing process. Glass fibers are first drawn into fine filaments and then formed into a mat using a needling or air-lay process. Optional binder materials may be applied to enhance cohesion, mechanical strength, and dimensional stability.

Step-by-Step Process:

1. Glass fiber production – drawing and chopping fibers

2. Forming – fibers arranged into a uniform mat

3. Needling/air-laying – bonding fibers mechanically

4. Heat setting – to stabilize the felt structure

5. Cutting and packaging – into rolls, sheets, or custom shapes

By following this process, Jiuqiang bur glass fiber felt achieves consistent thickness, density, and thermal performance.
