The face masks use the fabric as a middle layer and are highly breathable, washable and re-usable. They are designed to be used in the Indian healthcare market.
Permionics’ Perma Bioshield coated fabric is made by adhering an antimicrobial coating made of Ultrason E to the matrix of a non-woven fabric as a bonded support. BASF’s Ultrason E is a high purity material with low gel and oligomer content that ensures a stable membrane manufacturing process. PESU can be used in a wide pH range (0–13) without deterioration. It is especially suitable for the production of durable hollow-fibre membranes and filters for use in the food, beverage, electronics and pharmaceutical industries.
“In the Covid-19 pandemic, the need for developing and manufacturing high-efficiency particulate and bacterial filters for face masks has become a priority across the world. Ultrason E turns out to be an ideal choice for the coating of Perma Bioshield as the material allows for a better narrow pore size control and a good adhesion to non-woven fabrics. These are two features which are key to the removal of bacteria, dust and pollution,” said Satyajai Mayor, managing director of Permionics.
In addition to face masks, Perma Bioshield is also an ideal filter for breathable medical gowns and clothing used in hospitality and airline industries, high efficiency particulate air (HEPA) filter replacements, as well as antimicrobial and dust-proof blinds or screens.
