Finex was established in 1990 as a spin-off from Suomen Sokeri to develop and produce chromatographic separation resins and specialty polymers. The company provides tailor-made solutions for a wide range of customers, such as the food industry for the production of sugar and xylitol. Hartwall Capital invested in Finex in 2011 and sold its majority holding to Johnson Matthey (UK) in May 2016.
