HPQ Confirms Fumed Silica Produced With Pilot Scale Reactor is Independently Verified as Meeting Commercial Grade "150"

PYRGF
  • HPQ Silicon Inc. received independent verification from a potential customer under an LOI confirming that fumed silica produced by its Fumed Silica Reactor (FSR) meets or exceeds commercial grade "150" benchmarks.
  • Test #7 material achieved a specific surface area of approximately 150 m²/g via BET analysis while meeting required viscosity standards for commercial grade 150 fumed silica.
  • The pilot plant has fully replicated results from HSPI's original lab-scale tests, which were previously verified by McGill University, demonstrating the ability to produce hydrophilic fumed silica directly from quartz using a plasma-based system without chemicals or hazardous by-products.
  • Viscosity results at pilot scale are approximately 10% higher than the typical commercial grade 150 benchmark, indicating strong thickening efficiency and a well-developed three-dimensional network suitable for coatings, adhesives, sealants, inks, elastomers, and insulation binders.
  • The company scaled laboratory performance by approximately twentyfold while maintaining or improving key quality metrics, resulting in a process with a lower carbon footprint that avoids hazardous chemicals.
  • HPQ Silicon Inc. and technology partner PyroGenesis Inc. are advancing toward process optimization to maintain consistent production with a surface area of approximately 200 m²/g, representing commercial product grade 200.
  • The parties are preparing for continuous operation of the pilot plant to increase material availability for evaluation under non-disclosure agreements with potential partners in coatings, polymers, and advanced materials sectors.
  • Based on current results & market interest, HPQ Silicon Inc. has initiated planning activities toward a potential dedicated production site to progress the FSR program toward commercialization.
  • The global fumed-silica market is projected to surpass US$2.57 billion by 2034, driven by demand in coatings, sealants, automotive, and lithium-ion battery sectors.
  • HPQ Silicon Inc. is a Quebec-based industrial issuer focused on advanced materials, while PyroGenesis Inc. provides technical support leveraging 30 years of plasma technology leadership.
