Antimicrobial Additives for TPU Film in Medical and Outdoor Applications by Avient


Avient Corporation unveiled an expansion of its Cesa™ Withstand™ portfolio to include new grades of antimicrobial and antifungal additives. These new grades are developed to enhance the performance of thermoplastic polyurethane (TPU) film-laminated products and devices in applications where combating microbe development is highly important.  

TPU film is widely used as a waterproof or adhesive product layer in outdoor, medical, aviation, marine, and industrial markets. These new grades of Cesa Withstand antimicrobial additives can help limit microbial growth, which can lead to odor, staining, discoloration, or loss of mechanical properties in these applications.”

Cesa Withstand additives include organic and inorganic ingredients to inhibit the growth of bacteria, mold, and fungi on the plastic surface, providing uncompromising antimicrobial performance. The effective reduction of bacterial activity that can be achieved on TPU film laminated plastic and/or textile surfaces has been confirmed in extensive testing to international standards, including JIS 2801. The additives have also passed strict anti-fungus testing according to JIS Z 2911.

The two new available grades of Cesa Withstand for TPU film can meet the specific anti-bacterial and anti-mold protection needs of medical beds, transparent tent components, and ice bags. Other applications that can be further developed include portable energy storage, protective equipment, outdoor apparel, and air sleeping pads. They are currently manufactured in Asia and are commercially available globally.
