Parx Materials N.V. develops and commercializes biocide-free antimicrobial and antifouling polymer additives that prevent bacterial adhesion, biofilm formation, and microbial contamination on plastic surfaces through a proprietary biomimetic technology inspired by the human immune system. The company offers Saniconcentrate masterbatches and Passive Action Polymer Technology additives compatible with all thermoplastics for applications including food contact and packaging; medical devices and implants; textiles; pipes, drainage, and water infrastructure; consumer goods; aquaculture; and anti-fouling hygiene products to inhibit mold, fouling, and material deterioration. Parx Materials operates primarily in Europe with production scaling in Italy and partnerships in Norway; it was founded in 2012 and maintains headquarters in Rotterdam, Netherlands. In July 2024, GCP Technology AS, a Norwegian industrial group supported by local investors, acquired nearly 57% of the company's shares from founders Michael van der Jagt and Michele Fiori, who remain involved during the transition; GCP also assumed control of Parx's Norwegian partner ZincIn AS to leverage expertise. In December 2024, Parx Materials acquired its first production machine for a new scalable facility in Italy, initiating investments in equipment to establish in-house manufacturing, enhance capacity, and target growth in aquaculture, food packaging, and consumer sectors amid rising international customer interest. The company trades on Euronext Access Paris under ticker MLPRX.
