High-temperature resistant, flame resistant, abrasion resistant and chemical resistant for use in extreme environments.

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

Made with a wide variety of substrates, HYTEX® High Performance 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.
