The density of this product is 0.18-0.35g/cm3. The surface can be coated with graphite paper or carbon cloth, carbon cloth and graphite paper, graphite paper can be sandwiched between each felt. It can prevent surface fluff, gas leakage (convection), and protect its surface (prevent loss) and increase the strength of hard felt.
