Production Technique
Pertile is an acidic volcanic glass with pearl structure. After heating, it can expand to 12-15times, It possesses the characteristics of very light, thermal insulation,sound insulation, strong ab-sorption etc--- It is used in such industries as new build-ing materials, petroleum chemistry, metallurgy, casting, agriculture, food filter, and environment protection......
