Flexible Fabricated Products
Ceramic Fiber Vermiculite Cloth and Fiberglass Vermiculite Cloth
Code prefix VMC
This vermiculite cloth series uses bulked alkali-free fiberglass cloth and ceramic fiber cloth as base cloth and is made through finishing and vermiculite coating. The processing form can be customised to the working conditions. Ceramic fiber vermiculite cloth has a short-term tolerance of 1260 C and fiberglass vermiculite cloth 550 C. Graphite, silicone and acrylic coatings can be selected instead according to the environment, and the cloth can be pre-sintered to remove the organic components inside for high-temperature duty.

Two base cloths, one vermiculite finish
This vermiculite cloth series uses bulked alkali-free fiberglass cloth and ceramic fiber cloth as base cloth and is manufactured through finishing and vermiculite coating. The processing form can be customised to the working conditions. Ceramic fiber vermiculite cloth has a short-term tolerance of 1260 C and fiberglass vermiculite cloth 550 C. Graphite, silicone and acrylic coatings can be selected according to the environment, and a pre-sintering process can remove the organic components inside the cloth for high-temperature duty.
| Specification | Thickness (mm) | Width (mm) | Weight (g/m²) | Base cloth | Weave | Roll length (m) |
|---|---|---|---|---|---|---|
| CV2.0 | 2.0 | 1000 | 1200 | Ceramic fiber cloth | Plain | 30 |

Thickness, width and weight may vary by a reasonable tolerance of ±10 % in actual production.
Scope of application
Fire and smoke barriers, spark shielding, fire extinguishing protection and flexible expansion joint support for pipeline equipment, and as a thermal insulation supporting material for equipment and pipelines.
Working condition suitability and restrictions
A dry static insulation and fire protection material for room-temperature and high-temperature, pressure-free protection. It is not suitable for strong acid or alkali corrosion, high-speed medium erosion, continuous open flame burning, long-term liquid immersion or high-pressure loading. Fiberglass vermiculite cloth must not be used at ultra-high temperature, where the base material loses strength and fails.
Usage precautions
- Cutting and processing ceramic fiber products releases dust; ventilate, wear dust protection and dispose of waste under local environmental regulations.
- Base materials differ in temperature resistance; select against the actual condition and prohibit over-temperature use.
- Inspect regularly and replace when damaged, aged or detached.
- All technical data are for reference; users should test suitability and follow relevant safety regulations.
02 — Characteristics
Two base cloths
Ceramic fiber cloth at 1260 C short-term and fiberglass cloth at 550 C short-term.
Coating choice
Vermiculite finish as standard, with graphite, silicone or acrylic on request.
Sintered option
Pre-sintering removes organic content for high-temperature working conditions.
Six specifications
CV2.0, CV3.0, GV0.8, GV1.4, GV1.7 and GV2.0, all 1000 mm wide.
