The "Reliable Backbone" of Insulation: Purity Meets Performance:
Unlike standard mineral wool plagued by high slag content, Hebei Woqin uses a High-Purity Basalt formulation. We minimize non-fibrous waste to create a tighter fiber matrix, ensuring the board never sags, burns, or accelerates corrosion—even in the harshest industrial environments.
