Aladdin alumina fiber needle blanket is made of inorganic materials, free from binders and other components.
It can be used at temperatures up to 1500℃ for a long term.
The enhanced double-sided needle-punching process improves the interweaving degree of the fibers and the product's delamination resistance, providing good tensile strength without compromising its softness.
Aladdin alumina fiber needle blanket is independently developed and produced, and it has a national patent.
