Alumina Silica Fibre composes roughly of 70% Alumina and 30% Silica. The products / yarns are manufactured from 7 micron diameter filaments and are boron free. The 7 micron diameter ensure it maintains excellent flexibility and drapeability. Furthermore, its lack of Boron content ensures it has superior durability compared with other products presently available. Alumina Silica Fibre retails its mechanical strength close to 100% for temperatures up to 1200°C and can be used for applications close to 1395°C.
Alumina Silica Fibre products are available as woven cloth, braided sleeve, tape, rope, yarn and sewing thread.
