Vermiculite Coated Fibreglass Cloth is typically composed of two main components: fibreglass cloth and vermiculite coating.

Fibreglass Cloth: The base material of Vermiculite Coated Fibreglass Cloth is fibreglass, which is a woven textile made from fine strands of glass. Fibreglass cloth is known for its high strength, excellent thermal resistance, and durability.

Vermiculite Coating: The fibreglass cloth is coated with a layer of vermiculite, which is a naturally occurring mineral. Vermiculite is a hydrated laminar magnesium-aluminum-iron silicate mineral that expands when heated. It has excellent fire-resistant properties, making it an ideal coating for fibreglass cloth.

The vermiculite coating provides additional insulation and enhances the fire resistance of the fibreglass cloth. When exposed to high temperatures, the vermiculite expands, creating a protective layer that acts as a barrier against heat transfer and flame spread. It helps to reflect and dissipate heat, thus providing improved thermal protection.

It's important to note that the specific composition and ratio of fibreglass to vermiculite coating may vary among manufacturers or suppliers of Vermiculite Coated Fibreglass Cloth, so it's advisable to refer to the product specifications provided by the specific manufacturer or supplier for detailed information.
