Product Introduction
This fiberglass fabric is woven from glass fiber yarns. The material exhibits a low friction coefficient and does not readily adhere to other substances. The fabric provides fireproof, flame retardant, insulation, and pressure-resistant characteristics. It is used for thermal insulation, fireproofing, and flame retardant protection on hulls, storage tanks, cooling towers, ships, vehicles, tanks, and building materials. The normal operating temperature range extends from -180°C to +550°C.
Core Advantages
Wide Temperature Range
Operating temperature range from -180°C to +550°C, suitable for cryogenic and high-temperature applications.
Low Friction Coefficient
The fabric surface has low friction properties, preventing adhesion of materials such as adhesives, resins, and molten substances.
Fireproof and Flame Retardant
The glass fiber material does not support combustion. The fabric self-extinguishes when removed from flame sources.
Electrical Insulation
Provides dielectric insulation properties, suitable for electrical and electronic applications requiring non-conductive barriers.
Pressure Resistance
Woven construction provides mechanical strength to withstand pressure in insulation and protective covering applications.
Versatile Application
Applicable to hulls, storage tanks, cooling towers, ships, vehicles, tanks, and building materials for thermal and fire protection.
Product Features
Base material Alkali-free glass fiber (E-glass) yarns woven into fabric. Continuous operating temperature: -180°C to +550°C.

Application Scenarios
Ship hull thermal insulation
Storage tank fireproofing
Cooling tower panel covering
Marine vessel compartment protection
Vehicle engine compartment insulation
Storage tank thermal barriers
Building material fireproofing
Industrial equipment covers
This fiberglass fabric is suitable for marine applications including hull insulation to reduce heat transfer and provide fire barriers between compartments. Storage tanks use the fabric as an external fireproofing wrap for vessels containing flammable or high-temperature materials. Cooling tower applications include panel protection and weather barriers. Ships use the fabric for engine room insulation, exhaust system wrapping, and compartment fire barriers. Vehicles employ the fabric for engine compartment thermal management and exhaust heat shielding. Storage tanks for chemicals, oil, and gas benefit from the fabric's corrosion resistance and thermal protection. Building materials incorporate the fabric as a fire barrier layer in wall and ceiling assemblies. Industrial equipment covers and removable insulation blankets are also fabricated from this material.
Common Questions and Solutions
What is the difference between plain weave, twill weave, and satin weave?
Plain weave (1×1) offers the most stable structure and best dimensional stability, suitable for flat applications. Twill weave (2×2 or 3×1) offers better conformability around curves. Satin weave (4×1 or 8×1) provides the highest flexibility and drape for complex shapes. Choose based on the application geometry and required flexibility.
Does the fabric adhere to adhesives or coatings?
The fabric has a naturally low friction coefficient. For applications requiring adhesion to the fabric surface, surface treatment with coupling agents or primers is recommended. Silicone-based adhesives may bond more effectively than other adhesive types. Test adhesion on a sample before full-scale application.
Can the fabric be used for cryogenic applications at -180°C?
Yes. The glass fiber fabric maintains flexibility and mechanical properties at cryogenic temperatures down to -180°C. The material does not become brittle like many polymers. However, handle with care at cryogenic temperatures as the material may be less flexible than at room temperature.
Is the fabric suitable for outdoor or weather-exposed applications?
The uncoated glass fiber fabric is not recommended for direct outdoor exposure without protective coating. UV radiation can degrade the fiber sizing and reduce mechanical strength over time. For outdoor applications, request fabric with UV-resistant coating or specify a coated version such as silicone or acrylic coated fabric.
How should the fabric be cut and sewn?
Cut the fabric using sharp scissors, a rotary cutter, or a utility knife. For production quantities, use a die cutter or CNC cutting machine. Sew using high-temperature thread such as Nomex, fiberglass, or PTFE-coated thread. Use a needle size appropriate for fabric thickness (size 80-100 for thin fabric, size 110-120 for heavy fabric).
What safety precautions should be taken when handling fiberglass fabric?
Wear gloves, long sleeves, safety glasses, and an N95 respirator when cutting or handling fiberglass fabric to prevent skin and respiratory irritation. Wash hands after handling. Work in a well-ventilated area. The fabric releases small glass fibers when cut; clean work areas with a HEPA vacuum rather than sweeping to reduce airborne particles.
Installation and Handling Considerations
Store fiberglass fabric in a dry, clean area away from direct UV exposure. The fabric can absorb moisture from the air; allow it to dry before use in critical insulation applications.
When cutting the fabric, use sharp tools to minimize fraying. For clean edges, use a hot knife that melts the fiber sizing to seal the cut edges. Seal cut edges with high-temperature silicone or edge binding tape to prevent fraying in high-vibration applications.
For applications requiring waterproofing or chemical resistance, specify coated fabric (silicone, acrylic, PTFE, or polyurethane) instead of uncoated fabric. Coated versions provide additional protection but may have reduced temperature range depending on the coating material.
When installing over sharp edges or corners, use protective corner guards or multiple layers of fabric to prevent punctures. The glass fiber fabric can be cut by sharp metal edges under pressure.
For thermal insulation applications, install the fabric with the warp direction (lengthwise) aligned with the primary stress direction. The fabric has higher tensile strength in the warp direction than in the weft direction.
Inspect installed fabric periodically for damage including fraying, cuts, or discoloration. Replace sections that show significant wear. For fire barrier applications, replace any fabric that has been exposed to direct flame, even if no visible damage is apparent, as the glass fibers may have lost strength.
