Refractory Materials & Cements

Refractory materials — including insulating cements, gunning mixes, and castable refractories — were applied inside and around industrial furnaces, kilns, boilers, and high-temperature vessels. Many formulations manufactured before the mid-1970s incorporated chrysotile or amosite asbestos as a binder or heat-resistance agent.

Workers in steel mills, aluminum smelters, glass plants, and chemical facilities routinely applied, repaired, and removed these materials, often without respiratory protection. Asbestos exposure from refractory work is well-documented in industrial hygiene literature and asbestos litigation records.

Key product types in this category include spray-applied gunning refractories (Insulag, Kast-O-Lite), insulating cements applied to pipe fittings and valve bodies (A.P. Green Insulating Cement, Atlas Insulating Cement), and pre-formed insulating refractory brick containing asbestos fillers.

Manufacturers with active asbestos settlement trusts in this category include A.P. Green Industries (filed Chapter 11, 2002), Quigley Company (filed Chapter 11, 2004, Pfizer subsidiary), and Harbison-Walker Refractories.
