Fiberglass Fireproof Cloth: An Essential Fireproof Material

Fiberglass fireproof cloth plays an irreplaceable role in modern industry, construction, and daily life as a critical fireproof material. So, how should one choose fiberglass fireproof cloth?

1. Basic Concepts of Fiberglass Fireproof Cloth

Fiberglass cloth is a plain-weave fabric made from non-twist roving, produced through high-temperature melting, fiber drawing, spinning, and weaving processes using high-quality glass raw materials.

Its main characteristics include:

• High-temperature resistance: Can withstand temperatures ranging from -70°C to 550°C without burning.

• Non-flammability: Complies with Class A non-combustible material standards.

• Chemical stability: Resistant to corrosion and aging.

• Insulation properties: Excellent electrical insulation.

• Mechanical strength: High strength and tear resistance.

2. Production Process of Fiberglass Fireproof Cloth

• Raw material preparation: Selection of high-quality fiberglass yarn.

• Weaving process: Plain, twill, or satin weaving methods.

• Surface treatment: Coating with high-temperature-resistant materials such as silicone.

• Post-processing: High-temperature shaping, inspection, and rolling.

3. Applications of Fiberglass Fireproof Cloth

Industrial Sector

• Welding protection: Isolation of welding spatter areas.

• High-temperature pipe insulation: Insulation wrapping for oil and chemical pipelines.

• Electrical insulation: Insulation for transformers, motors, and other electrical equipment.

Construction Sector

• Fireproof curtains: Fire separation in public spaces like shopping malls and subways.

• Steel structure fireproofing: Slows down temperature rise in steel structures during fires.

• Ventilation duct fireproofing: Fireproof wrapping for building smoke control systems.

Fire Protection Sector

• Emergency tools: Fire blankets, escape route lining.

• Firefighter protection: Inner lining material for firefighting suits.

Other Sectors

• Automotive industry: Exhaust pipe heat insulation, battery pack fireproofing.

• Aerospace: Fireproof materials for aircraft interiors.

• Household items: Kitchen fireproof mats, fireplace protection.

4. Key Considerations for Choosing Fiberglass Fireproof Cloth

1. Define Usage Requirements

• Determine required temperature resistance.

• Consider environmental corrosiveness.

• Assess mechanical strength needs.

2. Quality Identification Methods

• Visual inspection: Smooth surface, no broken yarns, no stains.

• Touch test: High-quality products feel flexible and non-irritating.

• Burn test: Use a lighter—genuine products do not burn or produce open flames.

• Strength test: Try tearing—high-quality products resist tearing.

3. Certification Standards

• International certifications: UL94 V-0, EN 13501-1, etc.

4. Specifications Selection

• Thickness: Choose based on insulation requirements.

• Width: Consider construction convenience.

• Color: Common options include white, gold, and black.

5. Usage Precautions

• Safety protection: Wear gloves and masks during installation to prevent fiberglass irritation.

• Avoid direct skin contact, as it may cause itching.

6. Frequently Asked Questions (FAQs)

Q: What is the difference between fiberglass fireproof cloth and asbestos cloth?
A: Fiberglass fireproof cloth is non-toxic and eco-friendly, whereas asbestos cloth may release carcinogenic fibers. Fiberglass has slightly lower heat resistance than asbestos but is safer.

Q: Can fireproof cloth completely prevent fire spread?
A: Fireproof cloth can delay fire spread, buying time for evacuation and firefighting, but it cannot fully stop large fires. It should be used alongside other fire protection measures (e.g., SUNTEX automotive fire blankets).

Q: How to determine if fireproof cloth has degraded?
A: Severe brittleness, powdering, coating peeling, or exposure to temperatures beyond its rated limit may reduce performance.

7. Future Development Trends

• Composite materials: Enhanced performance through material combinations.

• Eco-friendly improvements: Reduced energy consumption and emissions in production.

• Smart integration: Incorporation of temperature-sensing and other smart functions.

• Multifunctionality: Combining fireproofing, waterproofing, and corrosion resistance.

As a crucial safety protection material, the selection and use of fiberglass fireproof cloth require professional evaluation based on specific applications. This guide aims to provide a comprehensive understanding of its features and uses, assisting in informed purchasing decisions.
