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

Executive Summary

• Independent verification confirms HPQ’s pilot‑scale fumed silica reactor (FSR) produces material meeting or exceeding commercial grade “150” specifications for surface area and viscosity.
• Test #7 achieved a specific surface area of ~150 m²/g and viscosity ~10 % higher than the typical benchmark, indicating strong rheology performance.
• The results validate scaling of HSPI’s plasma‑based process from lab to pilot scale and support further commercialization efforts, including larger production runs and potential dedicated plant.

Key Details

• Verification Source: Independent testing by a leading global fumed silica manufacturer under a Letter of Intent (LOI).
• Surface Area: Approx. 150 m²/g (meets/exceeds commercial grade “150” minimum).
• Viscosity Performance: ~10 % higher than typical commercial grade 150 benchmark, indicating superior rheology efficiency.
• Pilot Plant Scale‑up: Replicated lab‑scale results (originally verified by McGill University) at roughly twentyfold increase in production volume.
• Target Applications: Coatings, adhesives, sealants, inks, elastomers, insulation binders – where viscosity and surface area drive formulation performance.
• Future Goals: Achieve consistent production of ~200 m²/g (commercial grade 200) and transition to continuous operation for larger batch availability.
• Commercialization Path: Preparing material samples for NDA‑bound evaluation by potential partners; advancing discussions with a party under LOI; planning a dedicated production site.
• Market Context: Global fumed‑silica market projected > US$2.57 billion by 2034, driven by coatings, automotive, battery sectors.
