Thermal Ceramics FireMaster Bulk
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: FireMaster Bulk is used in UL Systems CAJ1053 and CAJ3032 for pipe and cable bundle penetrations. These UL systems have been tested to ASTM E814/UL1479. The bulk is a high-temperature fiber which is classified by Underwriters Laboratories (UL) under “Loose Fill Materials (BPHX)” in the UL Building Materials Directory, No. R9464. FireMaster Bulk is used as a fireproof fill, void, or cavity material for several UL systems. It is the base fiber for FireMaster products.

Features:

  • UL-classified, noncombustible material
  • Lightweight/flexible
  • Optional foil facing or encapsulation
  • Low thermal conductivity
  • Resists chemical attack
  • Unaffected by oil or water
  • Completely inorganic
  • Excellent acoustical properties
  • Applications:

  • Fill, void, or cavity material in through-penetration seals (firestops)
  • Seal duct, cable bundle, conduit, tubing, and cable tray penetrations
  • Information provided by Thermal Ceramics
