Heat Resistant Fabric and Textiles

HYTEX 1000 Woven Fiberglass Fabric

Mid-Mountain manufactures heat resistant fabric and textiles designed for use as thermal seals and thermal barriers in moderate to severe environments.

In 1976, we began manufacturing Channel Tapes and Tadpole Gaskets for use as seals in gas fireplaces and pellet stoves. Since then, we have engineered a wide variety of textiles used as thermal seals and thermal barriers across numerous industries.

Made with a wide variety of substrates, HYTEX® heat resistant fabrics and textiles have a continuous operating temperature from 400°F • 204°C to 5000°F • 2760°C (no oxygen present). Many standard products are available in configurations of knit or woven fabric, knit or woven tape, knit or braided rope (both round and square), and knit or braided sleeving.

We also have the capability to laminate with foil or pressure-sensitive adhesive or apply a specialty coating for applications that require increased heat, abrasion or chemical resistance.
