What Flexible Solutions International, Inc. does

In the company’s own words

Flexible Solutions International, Inc. (NYSE American: FSI) manufactures specialty chemicals and polymers for agricultural, industrial, consumer and water-management applications. Its products include thermal polyaspartates (TPAs), which help control scale and corrosion in oilfield and industrial water systems and support fertilizer use and crop nutrient management; nitrogen-conservation products that reduce fertilizer losses; and evaporation-control products for pools, reservoirs and irrigation infrastructure. The company also produces custom food and nutritional materials and serves customers through direct sales, distributors and private-label arrangements. Its product brands include HEATSAVR, WATERSAVR, SUN 27, N-Savr 30, EX-10, Amisorb, LYNX, MAGNET, AmGro and VOLT. Flexible operates through product lines rather than disclosing reportable segments, with TPA-related products forming its largest revenue-generating business. In 2025, it had 78 employees and generated revenue from product sales and research and development services. Its 1991 founding and 2004 acquisition of Donlar Corporation’s TPA patents and manufacturing facility helped shape its current business. Its website is www.flexiblesolutions.com.
