5N Plus (OTCMKTS:FPLSF) is a Canadian specialty chemicals and materials company that develops, manufactures and commercializes high‐purity metals and compounds for advanced technology markets. The company’s product portfolio spans a range of elemental metals—including bismuth, antimony, tellurium, selenium, indium and germanium—along with organometallic precursors, catalysts and radioisotopes. These materials are engineered to meet stringent purity standards (commonly known as “five‐nines” or 99.999% purity) for critical applications in electronics, photovoltaics, catalysts and life sciences.
Founded in 2000 and headquartered in Boucherville, Quebec, 5N Plus has grown from its roots in high‐purity research to a global manufacturing and distribution platform. The company operates multiple production and R&D facilities across North America, Europe and Asia, enabling it to serve regional supply chains and maintain consistent quality control. Over the years, 5N Plus has invested in proprietary purification technologies and analytical laboratories to support customers’ evolving specifications in semiconductor wafer fabrication, solar cell production and pharmaceutical research.
5N Plus’s product offerings address diverse end markets. In the renewable‐energy sector, its high‐purity tellurium and selenium compounds are used in thin‐film photovoltaic modules. In electronics, indium and gallium precursors support compound‐semiconductor devices, while its antimony‐ and bismuth‐based materials serve as flame retardants and chemical catalysts. The company also produces radioisotopes for medical imaging and specialty reagents for academic and industrial research labs. Across all segments, 5N Plus emphasizes ISO‐certified processes and rigorous testing protocols to ensure product consistency and traceability.
Led by a management team of chemists and materials‐science specialists, 5N Plus continues to pursue growth through innovation and geographic expansion. Strategic partnerships with research institutions and targeted capacity additions underscore the company’s commitment to meeting the rising demand for ultra‐high‐purity materials in emerging technology sectors worldwide.
