Using Coated Fabrics in High Temperatures

Coated fabrics are used in a variety of applications, in industries such as welding, robotics, and aerospace. Coated fabrics that are used in high-temperature applications can be made with varying compositions to offer a range of different advantages

Silicone rubber offers vast benefits when used to coat fabrics for high temperature applications. High level of thermal resistance is offered by the material – in temperatures up to 572 °F, and it often displays superior creep, elongation, thermal conductivity, fire resistance, and tear strength on exposure to these extreme temperatures.

Besides heat resistance, silicone also has a high level of abrasion and chemical resistance. Mid-Mountain Materials, Inc.’s silicone coated fabrics can be used for thermal insulation barriers, weld spatter protection, and removable pad insulation.

Refractory Compound

The strength of refractory compounds is not compromised at high temperatures – even above 1000 °F – hence refractory coated fabrics are often used in applications which require high strength.

Refractory coated fabrics are extensively used for ovens, kilns, and furnaces, owing to their high temperature resistance. Further applications include abrasion-resistant curtains, seals, and expansion joints.


Vermiculite undergoes considerable expansion on heating, making it a popular option for barriers and seals in high-temperature applications.

‘Firestar Fabrics’ is the Mid-Mountain range of vermiculite coated fabrics. They are made up of a fiberglass substrate coated with vermiculite that improves the resistance against flame impingement, burning, molten splash, corrosion, and sparks.

Moreover, this coated fabric has great thermal insulation properties, enabling its use in applications requiring heat resistance, for instance, continuous furnaces that have both hot and cool sections.


Ceramic coated fabrics are a sought-after choice for high temperature applications as they offer numerous preferred properties including low thermal conductivity, excellent wear resistance, and high strength.

Mid-Mountain’s ceramic coated fabrics have improved dimensional stability and strength; the fabrics also do not fray as easily, and have superior heat and weather resistance.

Ceramic coated fabric applications generally include insulation pads, thermal insulation seals, and molten metal splash protection.
