[{"type":"text","content":"HPQ Confirms Fumed Silica Produced With Pilot Scale Reactor is Independently Verified as Meeting Commercial Grade “150”New commercial milestone reached, lab scale results fully replicated\nMONTREAL, Jan. 30, 2026 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. (“HPQ” or the “Company”) (“HPQ” or the “Company”) (TSX-V: HPQ, OTCQB: HPQFF, FRA: O08), a technology company driving innovation in advanced materials and critical process development, is pleased to announce that it has recently received independent verification of its most recent test results from a potential customer, under LOI [1]. These results confirmed that the fumed silica produced by HPQ’s fumed silica reactor (FSR) meets or exceeds commercial product grade “150”. Specifically, the potential customer has confirmed that the material produced during the previously announced Test #7 meets established commercial benchmarks for fumed silica with a specific surface area (under BET analysis) of approximately 150 m²/g, while at the same time also achieving the required viscosity for that commercial grade. With this confirmation, the pilot plant has now fully replicated the results produced by HPQ Silica Polvere Inc.’s (HSPI) [2] original lab-scale tests. These tests, which were verified by McGill University, were the first results which indicated the possibility of producing commercial grade fumed silica from quartz using a plasma-based system. In the company’s opinion, today’s announcement further validates the potential commercial performance of HSPI’s proprietary plasma-based process for producing hydrophilic fumed silica directly from quartz, without the use of chemicals, while creating no hazardous by-products. The Importance of Reaching the Viscosity Milestone In commercial applications such as coatings, adhesives and sealants, inks, elastomers, and insulation binders, viscosity, often referred to as rheology efficiency, is a critical performance metric for fumed silica because it governs thickening, suspension stability, and application behavior. For many applications, viscosity performance at a given surface area can ultimately determine functionality in end-use formulations. Results show that the viscosity achieved by the FSR at pilot scale is ...
