Americhem Creates Line Of Antimicrobial Masterbatches

Cuyahoga Falls, Ohio-based Americhem Inc. – a provider of custom color and additive solutions – has
developed a full line of antimicrobial masterbatches for fine-denier polyester, nylon and
polypropylene fiber applications. The masterbatches feature better dispersement, higher efficacy
and lower abrasion than their predecessors, according to the company.

“Americhem continually works to raise the bar in the fibers industry,” said Dr. Vaman G.
Kulkarni, technical marketing director for Fibers, Packaging and Films, Americhem. “Americhem has
been active in antimicrobial masterbatches since 2003. One of the challenges with melt-spun
antimicrobial additives has been achieving dispersion quality suitable for fine-denier applications
and lower abrasion.”

“The high concentration of silver in antimicrobial masterbatches provides cost-effective
inhibitory activity against a wide range of microorganisms including bacteria and fungi, among
others,” said Roger Threadgill, technology manager, Americhem.
