Refractory Coated Glass Cloth

Refractory Coated Glass Cloth

Refractory coated glass cloth is treated with vermiculite on both sides, providing exceptional resistance to high temperatures. The mineral based aqueous dispersion treatment of vermiculite provides a coating of platelets which meld at elevated temperatures. This helps to protect the base glass cloth material from direct heat sources, such as molten metal and solder. Due to these properties, refractory coated glass cloth is commonly used in the manufacture of welding blankets and high temperature connectors and sleeves in the metal and foundry industry.

Refractory coated glass cloth can be supplied cut to size, by the roll, or manufactured to suit your bespoke requirements. It is also available to buy online at PAR Direct by clicking the link above.
