Silicone Coated Glass Fibre Fabrics Up to 550°C
WITH SILICONE RUBBER COATING
Glass fiber fabrics, 0.2mm, 0.5mm, 0.8mm, with silicone rubber coating on one side and both sides, possess the functions of flame retardancy, water repellency, oil resistance, thermal insulation, electrical insulation, high strength, anti-slip, and heat- and corrosion-resistance.
Applications:
They are utilized in cars, boats, vessels, airplanes, power plants, pipelines, and other applications where thermal insulation and flame retardancy are necessary.

|---|---|---|---|---|---|
| 7628# | 100% glass fibre | Silicone rubber, both sides | 260 g/m² | 50″, 59″ | Lightweight duct connectors and thermal wraps |
| 3732# | 100% glass fibre | Silicone rubber, both sides (double layer option) | 580 g/m² | 39″, 50″, 59″ | UL94 V0, 260 °C continuous / 550 °C peak |
| 3784# | 100% glass fibre | Silicone rubber, both sides | 1150 g/m² | 39″, 59″ | Heavy duty welding protection and expansion joints |
Available in 0.2 mm, 0.5 mm and 0.8 mm thickness grades, coated on one side or both sides. Contact us with your target thickness and we will confirm the matching model.
Where Silicone Coated Glass Fibre Fabric Is Used
Welding blankets and welding protection
The 580 g/m² (3732#) construction is the usual choice for welding blankets: it absorbs spatter, tolerates short-term peaks of 550 °C and stays flexible enough to be folded and re-used on site. Heavier 1150 g/m² (3784#) is specified where spatter volume and abrasion are high.
Fabric expansion joints and duct connectors
Expansion joints in flues, pipelines and power plants need a cloth that survives heat cycling while still moving with the equipment. 3732# and 3784# are used for expansion joints; the lighter 260 g/m² 7628# is used for flexible duct connectors between fans and ductwork, where the fabric must absorb vibration and still fold tightly.
Fire curtains, smoke curtains and thermal insulation
Because the cloth is flame retardant and rated UL94 V0, it is used for fireproof and smoke curtains, thermal insulation jackets, mattresses and covers for equipment in cars, boats, vessels, airplanes, power plants and pipelines.
Escape cloaks and fire survival blankets
Double-sided, double-layer silicone coating gives a sealed, comfortable surface on both faces, which is why it is used for escape cloaks, fire emergency survival blankets, full body protection and home escape suits.
How to Choose the Thickness (0.2 / 0.5 / 0.8 mm)
- 0.2 mm — flexible duct connectors, small thermal wraps and gaskets where weight and foldability matter most.
- 0.5 mm — general-purpose grade for welding blankets, expansion joints and insulation jackets.
- 0.8 mm — heavy duty, for frequent welding, high mechanical abrasion and curtains that must stay rigid.
Frequently Asked Questions
What temperature can silicone coated glass fibre fabric withstand?
It withstands continuous temperatures up to 260 °C, and short-term peaks up to 550 °C and above, depending on the model.
Is it flame retardant?
Yes. The 3732# double-sided double-layer construction is rated UL94 V0 and the glass fibre base does not support combustion.
Single sided or double sided coating?
Single sided coating is used where the fabric is sewn, clamped or bonded on the uncoated face. Double sided coating seals both faces against water, oil and spatter, and is the standard choice for escape cloaks and welding blankets handled from both sides.
What widths are available?
House widths are 39″, 50″ and 59″ (about 1.0 m, 1.27 m and 1.5 m). Tell us the panel size you need and we will advise on roll width to minimise waste.
