Vermiculite, when dipped and coated on to glass fabric, produces a material with temperature resistance of 1000˚C for 30 minutes. At this temperature the vermiculite fibres melt to form a protective layer through the fabric, thereby giving this outstanding technical characteristic. The fabric colour is golden, with visible vermiculite fibres.
Our vermiculite dipped glass fabric uses Dupré Micashield as the vermiculite dispersion. With carefully controlled Micashield fibre grading and a purpose built Compotex production machine, Compotex vermiculite dipped glass fabric is valued for its performance and reliability.
It is an excellent product for the protection of machinery and people in processes that create welding sparks or molten metal splashes.
The most common vermiculite dipped fabrics are heavy resilient fabrics of weight between 1000 and 1500 g/sqm. Micashield technology can also be used with lighter glass fabrics, and with silica fabrics for more challenging temperature environments.
Micashield is a registered trademark of Dupré Minerals.

With carefully controlled Micashield fibre grading, Compotex vermiculite dipped glass fabric is valued for its performance and reliability.
We were asked to put a vermiculite coating on to new 2000 g/sqm glass fabric; our standard vermiculite dipped fabric is 1000 to 1500 g/sqm.
Handling heavy fabrics is not a problem for Compotex. Our graphite coatings are often on to very heavy fabrics, but it is less common for vermiculite coatings.
Our vermiculite production is on a dedicated production line, so we arranged to do a small production run to our standard specification. This specification gives heat protection of 1000˚C for 30 minutes. In discussions with our customer, we agreed that the standard Compotex specification for our Micashield vermiculite coating should work well.
An initial small order was placed and we were able to run the production trial alongside existing production as the dip specification was the same.
