Abstract

When mineral wool articles are heated, organic compounds are released into the gas phase due to the pyrolysis of the polymer binder beginning at 240°C. There are two temperature ranges of pyrolysis: mostly oxygen-free hydrocarbons are observed in the products below 400°C, and oxygen-containing hydrocarbons, above this temperature, in the case of an oxidizing atmosphere. Mineral wool articles contain more than 5 wt % polymer binder. Aluminosilicate fibers have amorphous structure and crystallize into the augite phase when heated to above 850°C.
