This silicone rubber fiberglass fabric is manufactured from fiberglass cloth coated with silicone rubber. The material exhibits lightweight construction, high strength, corrosion resistance, water and oil repellency, non-combustibility, no dripping under fire conditions, no shrinkage or elongation when exposed to flame, and low smoke emission. The fabric serves as a fire-resistant and flame-retardant material. Performance indicators include combustion performance meeting UL 94V-0 standard, tensile strength of ≥17.6 kgf/cm, excellent aging resistance, non-toxic composition, and environmental compliance. Applications include welding curtains for industrial and mining enterprises, fire and smoke-resistant inorganic roller shutter materials, insulation covers for heaters and freezers, and custom-processed fire blankets, fireproof covers, and other shapes according to user requirements.

Application Scenarios

Welding curtains for industrial and mining enterprises

Fire and smoke-resistant inorganic roller shutters

Insulation covers for heaters and freezers

Fire blankets for emergency use

Fireproof equipment covers

Expansion joint covers

Heat shield curtains

Marine and offshore fire barriers

This silicone rubber fiberglass fabric is suitable for welding curtains in industrial and mining enterprises, where the material shields workers from UV radiation and welding spatter while providing flame resistance. Fire and smoke-resistant inorganic roller shutters use the fabric as the curtain material, meeting building code requirements for fire-rated openings. Insulation covers for heaters and freezers utilize the material's thermal insulation properties and weather resistance for equipment protection. Fire blankets for emergency use are fabricated from the fabric for industrial and marine applications. Fireproof equipment covers protect pumps, valves, and instruments during hot work operations. Expansion joint covers in building construction and industrial facilities use the flexible fabric to accommodate movement while maintaining fire resistance. Heat shield curtains protect control panels and personnel from radiant heat. Marine and offshore applications use the fabric for fire barriers in engine rooms and accommodation areas.

Common Questions and Solutions

What does UL 94V-0 flame rating mean?

UL 94V-0 is the highest flame rating for vertically oriented materials. The material must self-extinguish within 10 seconds after two 10-second flame applications, produce no flaming drips that ignite cotton, and show no glowing combustion beyond 30 seconds. This silicone rubber fiberglass fabric meets all requirements for V-0 classification.

Is the fabric suitable for outdoor use?

Yes. The silicone rubber coating provides excellent UV resistance, water repellency, and weather resistance. The fabric maintains flexibility and mechanical properties after prolonged outdoor exposure. For continuous outdoor use, the red color may fade over time, but this does not affect fire resistance or mechanical properties.

Can the fabric be washed or cleaned?

The fabric can be cleaned by wiping with a damp cloth and mild detergent. Do not machine wash or submerge the fabric for extended periods. For welding curtains, periodically wipe off accumulated spatter. For oil-contaminated fabric, use a mild degreaser and rinse with water, then air dry.

What thickness should I choose for welding curtains?

For light-duty welding protection (occasional use), 0.5-0.8mm thickness is sufficient. For heavy-duty welding environments (daily use, high-amperage welding), 1.0-1.5mm thickness provides better spatter resistance and longer service life. For welding curtains requiring higher light blocking, darker colors such as black provide better UV absorption than red.

Does the fabric produce toxic fumes when heated?

The silicone rubber coating produces minimal smoke and does not release halogenated gases. Under fire conditions, the material decomposes into carbon dioxide, water vapor, and silica dust. The fabric is non-toxic and environmentally friendly under normal use. For applications with direct flame contact, adequate ventilation is recommended.

How should the fabric be fabricated and installed?

Cut the fabric using sharp scissors or a utility knife. Sew using high-temperature thread (Nomex, fiberglass, or PTFE-coated) for applications up to 260°C. For higher temperature applications (above 260°C), use stainless steel wire for seams. For roller shutter applications, the fabric must be securely attached to the roller tube and bottom bar using mechanical fasteners or high-temperature adhesive.

Installation and Handling Considerations

Store the fabric in a dry, clean area away from direct UV exposure when not in use. The silicone coating may pick up dirt if stored on dirty surfaces.

For welding curtain applications, install the curtain with the coated side facing the welding operation. The smooth silicone surface allows spatter to be easily wiped off. Ensure the curtain is grounded according to safety standards for welding operations.

For fire roller shutter applications, ensure the fabric is installed with proper tension and overlap at side guides. The fabric must be able to roll smoothly onto the roller tube without wrinkling. Test the shutter operation before final commissioning.

When fabricating fire blankets or covers, use double-stitched seams for strength. Grommets should be installed at 30-50cm intervals for hanging applications. Use stainless steel or brass grommets; do not use plastic or aluminum grommets.

Do not use the fabric in continuous contact with molten metal. The fabric can withstand short-term spatter but will degrade under direct molten metal flow. For molten metal splash applications, use a thicker version or multiple layers.

Inspect the fabric periodically for damage, particularly in welding curtain applications where spatter may accumulate. Replace sections that show visible wear, holes from spatter, or degradation of the silicone coating. For safety-critical fire barrier applications, replace the fabric at regular intervals per facility maintenance schedule.
