Rock Wool Board
Puruide rock wool product is made of select fine basalt as the major materials which is pulled into 4-7µ non-continuous fibers after melted by adopting advanced international four-roller centrifugal cotton-making procedures and adding a certain of adhesives, dust laying oil and water repellent into rock wool fibers.
