ALUMINA FIBER BLANKET

Descriptions

DAYAWOOL ALUMINA FIBER BLANKET, firstly appeared in 1950s, and be industrialised produced at the begining of 1970s. According to different fiber length, it is classified to catagories---continuous long fiber and short fiber, Alumina fiber blanket belongs to short fiber product, and Alumina fiber cloth belongs to long fiber product. Alumina fiber is manufactured by “Sol-Gel” colloidal method, to be Microcrystalline mullite phase high temperature refractory fiber through high-temperature calcination. Alumina fiber blanket is manufactured from Alumina fiber by doubled needled, doesn’t contain any additives or other ingredients.
