Vermiculite Coated Fiberglass:
FlameShield™ 1500 - Very High Temperature, Heat & Flame Resistant Thermal Insulating Tape
This high temperature, heat and flame resistant thermal insulating vermiculite coated fiberglass tape will withstand temperatures of 1500°F / 815°C continuous exposure.  The base High Temperature braided fiberglass sleeving is fabricated from high quality type E fiberglass that will not burn.  The sleeve is then coated with a vermiculite dispersant.

This material resists most acids and alkalis and is unaffected by most bleaches and solvents.  It is highly flexible and conformable.
Very High-Temperature Vermiculite Coated Fiberglass Tape
Applications for this product include thermal insulation and/or protection of wires, cables, hoses, pipe and tube, as well as affording energy savings and personnel protection.

The vermiculite coating also adds abrasion resistance to the sleeve.

The tape is available in Plain and Drop Warp Styles.  Drop Warp tape has several of the center lengthwise yarns missing during weaving, and allows the tape to be easily used for bolt-hole applications (sometimes called ladder tape).

Tested and certified to meet the standards of ASTM E 162, ASTM E 662 and SMP 800C.
