Synvina is a 100% owned company of Avantium. Synvina aims to become market leader in the production and marketing of furandi­carboxylic acid (FDCA), which is produced from renewable resources, as well as the marketing of the new polymer polyethyl­enefuranoate (PEF). FDCA is a building block for various products, most significantly the polyester PEF, which is suitable for use in the packaging industry, for example. By offering superior characteristics such as improved barrier properties and higher mechanical strength compared to conventional plastics, PEF challenges long-established products like conventional PET, aluminum or glass bottles.
