face-maskSukano has conducted further tests after results confirmed the effectiveness of SUKANO® high performance Antiviral 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.

Excellent Effectiveness Within the First 30 Minutes


The results confirmed the excellent effectiveness of the Masterbatches - within the first 30 minutes an achievement of up to 99.9 % reduction on any fabrics item'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,” added Kirch.

Allows Final Products to be Reusable and Recyclable


Sukano’s Antiviral Masterbatches work by directly integrating an antiviral additive into the polymer, using proprietary formulation and technology, eliminating the need for secondary processing steps. This helps the environment by reducing waste and energy, saving natural resources.

The SUKANO® Antiviral Masterbatch allows the final product to remain fully recyclable without a loss in performance, contributing to the common goal of a circular economy. The Antiviral Masterbatch is extremely efficient and this powerful technology remains present and effective throughout the life of the product. The antibacterial efficacy was tested and remained after up to 200 washing cycles at 40° C. All this is possible without impacting the fibers’ physical properties or yellowing.

Registered Preservative


The active ingredient used in Sukano’s Antiviral Masterbatches is a registered preservative in the EU, Switzerland and USA. However, to claim antiviral effect and promote this in the final product, producers using Sukano’s Antiviral Masterbatches must test the final product, have the results confirmed by a specialized external laboratory, and must comply with local legal regulations.
