A mat based on high silica fibers, mechanically bonded with the aid of needles.
It can resist high temperature of 1000 degree C and be cut into different thickness according to the requirements of customers.As an excellent heat insulation material, the silica fiber cotton has innumerable tiny air pockets.
When the sound wave enters the silica fiber cotton, its energy will be absorbed by the cotton due to the friction between fibers and different sizes of air pockets.It is a good material for preventing the interference of noise.
