we are themanufacture of Cenospheres,the melting point of
1600-1700, the Sub-heated expansion of the obturator from the ball,
there are many within the hole, with the noise absorption, strong
absorption of the characteristics of silicate hollow ball with a
low hardness, The proportion of light, particle size, and the
characteristics of high porosity, Applied Materials by the
permeability and reduce production at the crack and let bubble
phenomenon and improve performance
