Sukano masterbatches demonstrate long-term antiviral effect

Many viruses have been shown to survive on surfaces including metal, cardboard and plastic. However, plastic items can be treated to trap and inhibit the replication of viruses. Sukano has developed antiviral masterbatches for PET and PA fibres that have a strong antiviral effect on the plastic parts, while also potentially helping to reduce waste and improve the sustainability credentials of the final articles produced.

Sukano’s masterbatches work by directly integrating an antiviral additive into the polymer, using proprietary technologies. The power of this technology is that the antiviral effect not only remains stable during the usage of the product, but that it is maintained after washing. This is because the additive is consistently present on the surface of the product, without being released into the environment.

Sukano conducted tests at an external laboratory specialized in microbiological testing and in accordance with ISO 18184:2019 (fabrics) and ISO 21702:2019 (plastics injection moulded parts and films) to independently confirm the effectiveness of its antiviral effect on the plastic parts. The result showed that over 98% of the Feline Coronavirus was eliminated within the first two hours. The tests were performed using the Influenza H1N1 virus and a Feline Coronavirus, which has structures and mechanisms similar to SARS-Cov-2.

Alessandra Funcia, Head of Marketing and Sales, said: “Our SUKANO antiviral masterbatch is already in use by our existing customers who have successfully and effectively produced face masks during the pandemic outbreak. We now have additional, external lab results to back up our claims regarding its antiviral effect. The masterbatch is readily available from our stock to support the significant market demand.”
