ALSIFLEX® is a refractory high temperature wool based on aluminium and silicum oxide. ALSIFLEX®-1260, -1400 and -1430 are aluminium silicate wools.

ALSIFLEX®-1600 is a polycristalline wool based on mullite and corund. ALSIFLEX® wools are lightweight, flexible insulating materials with high permanent temperature resistance, low thermal conductivity and partly high chemical resistance.
