South Korean antiviral masks materials production

SK Chemicals is expanding its supply of transparent materials ‘SkyGreen’ to the United States and Europe, doubling the volume over the last year. 

SK Chemicals said that “due to the shortage of personal protective equipment in the US and Europe high volumes are being dispatched.” SkyGreen is also used in food and cosmetics packaging.

As the response to Corona virus in the United States and Europe is strengthening, demand for local medical equipment and personal protective equipment is growing. In particular, as the use of face shields and transparent anti-glare windows increases with the use of masks, the demand for transparent materials is increasing.

SkyGreen, which SK Chemicals succeeded in commercializing, is regarded as the most suitable material for personal protective equipment such as face shields and transparent anti-glare windows, based on glass-like transparency and the highest level of chemical resistance.

It has the world’s top 3 safety certifications, issued by U.S. Food and Drug Administration (FDA), the European Food Safety Authority (EFSA), and the Japan Hygiene Balance Association (JHOSPA), and can be used for products that directly contact skin or food. It also does not contain BPA.

When other general-purpose transparent materials with low chemical resistance are used in protective equipment for frequent disinfection and cleaning, the ‘crack phenomenon’ in which the equipment itself cracks and a ‘blurring phenomenon’ in which the color changes to blue occurs. 

Another South Korean company, Daewon Hwasung, specializing in polyurethane materials, develops and sells new polyurethane materials for masks.

Daewon Hwasung achieved know-how in polyurethane processing technology through engagement in automotive, IT, and sports industry segments.

The mask material developed has excellent antibacterial properties and can be reused after washing. It is also environmentally-friendly and it does not use any chemicals that are harmful to human health. Its performance has been verified in KATRI (Korea Apparel Testing Research Institute) and  FITI Test Research Institute.

Daewon Hwasung plans to further develop and sell finished masks based on the material.
