  • Premium Quality: DFP offers top-tier Silica ramming mass pre-mixed with Boron Oxide, ideal for Cast Iron and SG Iron Foundries.

  • Source Excellence: Our silica is sourced from the finest mines in Germany and Sweden, renowned for the world’s best quality.

  • Enhanced Density: By blending silica from these two locations, we achieve superior packing density.

  • Superior Binder: Utilizing 200 mesh boron oxide as a binder, DFP silica boasts higher packing density and binding strength.

  • Proven Performance: DFP silica has demonstrated exceptional performance across various applications.

  • Advanced Material: Our fused silica offers significantly lower expansion compared to natural silica.
