BASF has joined hands with membrane manufacturer Permionics Membranes, Vadodara, India to extend the application of BASF’s Ultrason E (PESU: polyethersulfone) into coated fabrics which serve as particulate and bacterial filter for face masks.

The face masks using the fabric as a middle layer are highly breathable, washable and re-usable unlike conventional face masks. They are designed for the usage in the Indian healthcare market.

Permionics selected Ultrason E for its coated fabric called Perma Bioshield. The unique protective fabric is made by adhering an anti-microbial coating made of Ultrason E to the matrix of a non-woven fabric as a bonded support. Ultrason E is a high-purity material with low gel and oligomer content that ensures a stable membrane manufacturing process.

The BASF PESU can be used in a wide pH range (0 - 13) without deterioration. It complies with Food and Drug Administration (FDA) and European standards for repeated-use food contact and thus can be used in drinking water and food processing applications. It is especially suitable for the production of durable hollow-fiber membranes and filters for use in the food, beverage, electronics and pharmaceutical industries.

“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,” brought up Satyajai Mayor, managing director of Permionics.

Currently, the Perma Bioshield is used in several types of face masks in India, manufactured by a leading healthcare company. Apart from being used in face masks, Perma Bioshield is also an ideal filter for applications such as breathable medical gowns and clothing used in hospitality and airline industries, high efficiency particulate air filter (HEPA) filter replacements, antimicrobial and dust-proof blinds or screens.
