文摘
FRAB and rock wool display different temperature-induced behavior. FRAB devitrifies into carcinogenic cristobalite at high temperature (1400 °C). Potential health hazards exist during fire cleanup of FRAB-insulated buildings. Being a composite material, FRAB exhibits a two-step sintering behaviour. Flammability test results mirror breakdown of organic matter.
