Flexible Fabricated Products
Fiberglass Silicone Cloth
Code prefix GSC
Fiberglass silicone cloth conventionally uses alkali-free fiberglass cloth as the base and is made through finishing and silicone coating. The processing form is customised to the working conditions, and graphite, acrylic or PU coatings can be applied instead as required. Ceramic fiber cloth, bio-soluble fiber cloth or steel wire reinforced glass cloth can be selected as the base. Conventional alkali-free glass base has a short-term tolerance of 550 C and cannot run continuously at that temperature; a higher-temperature base improves the overall rating.

01 — Product description
Silicone face on a glass base
Fiberglass silicone cloth conventionally uses alkali-free fiberglass cloth as the base and is manufactured through finishing and silicone coating, with the processing form customised to the working conditions. Graphite, acrylic or PU coatings can be applied instead as required, and ceramic fiber cloth, bio-soluble fiber cloth or steel wire reinforced glass cloth can be selected as the base. Conventional alkali-free glass base has a short-term tolerance of 550 C and cannot operate continuously at that temperature; a high-temperature resistant base improves the overall rating.
| Specification | Thickness (mm) | Width (mm) | Weight (g/m²) | Weave | Coating | Roll length (m) |
|---|---|---|---|---|---|---|
| GS230 | 0.2 | 1270 | 230 | Plain | Single side | 200 |
| GS270 | 0.2 | 1270 | 270 | Plain | Double side | 200 |
| GS480 | 0.4 | 1000 | 480 | Twill | Single side | 100 |
| GS530 | 0.5 | 1000 | 530 | Twill | Double side | 100 |
| GS850 | 0.8 | 1000 | 850 | Satin | Double side | 50 |
Thickness, width and weight may vary by ±10 % in production, and non-standard specifications can be customised.
Scope of application
Smoke curtain wall fabrication, fire and smoke barrier protection and spark shielding, fire extinguishing protection blankets, flexible expansion joint support for equipment and pipelines, and thermal insulation and fire protection for equipment and pipelines.
Working condition suitability and restrictions
Suitable for dry static fire protection, thermal insulation, smoke barrier and spark conditions. The silicone coating does not resist continuous open flame burning, strong acid or alkali corrosion, high-speed airflow and medium erosion or long-term high-pressure mechanical friction, and the product is not suitable for long-term liquid immersion or continuous over-temperature operation. Base materials differ in temperature resistance, so the base grade must match the site condition.
Usage precautions
- Cutting and processing releases fiber dust; ventilate, wear dust protection and dispose of waste under local environmental regulations.
- 550 C is the short-term tolerance of the alkali-free glass base; over-temperature long-term use is strictly prohibited.
- Inspect regularly and replace when the coating or base is damaged, detached or aged.
- All technical data are for reference; users should test suitability and follow relevant safety regulations.

Service limits
- The silicone coating does not resist continuous open flame, strong acid or alkali, high-speed airflow and media erosion or long-term high-pressure friction.
- Not for long-term liquid immersion or continuous over-temperature operation.
- 550 C is the short-term tolerance of the glass base; long-term over-temperature use is prohibited.
- Cutting releases fiber dust; replace when the coating is damaged, detached or aged.
