The ongoing COVID-19 pandemic has helped raise awareness about the importance of hygiene and health all over the world. The demand for surfaces that do not play a possible role in transmitting a virus has increased - be it in packaging, textiles, industrial or medical applications.


SUKANO® high performance Antiviral Masterbatch is designed to do exactly this: protect surfaces from acting as a transmitter. This makes our product key for environments that require with highest hygiene and sanitary standards, such as the medical, hospitality, sports and events industries.


Sukano conducted further tests after the last year´s results confirmed the effectiveness of the masterbatch against Feline Coronavirus and Influenza H1N1. The company has now run extensive tests against SARS-Cov-2 in an external laboratory specialized in microbiological testing. The results confirmed the excellent effectiveness of the Masterbatches - within the first 30 minutes an achievement of up to 99.9 % reduction on an fabrics items's surface and a reduction up to 99.98 % within 2 hours.


“We extended the tests beyond PET and PA to PP and PLA, and also tested specifically against SARS-Cov-2 according to ISO standards” states Michael Kirch, Global Head of R&D for Sukano. “These tests confirm the same robust and efficient results. We are delighted with the outcome of the tests and have now confirmation on the deactivation of the viruses on fabric surfaces by a certified and specialized external laboratory, giving our customers additional trust and confidence to use our high performance additive masterbatch in their applications.”
