Americhem nShield® Antimicrobial Additives

Americhem’s nShield® antimicrobial additives create proven, long-lasting surface protection that enhances your product’s integrity and your brand’s value. 


In today’s germ-conscious world, consumers are searching for products that contain proven antimicrobial solutions. Americhem answers this rising demand with nShield®, our antimicrobial additive technology that’s customized to meet your unique end-use requirements. Untreated plastics harbor bacteria, mold, mildew, fungi and algae. These harmful microbes cause unsightly discoloration and material degradation over time – especially in outdoor environments. Adding nShield® will inhibit microbe growth, helping to extend your product’s life expectancy. Our advanced antimicrobial polymers also enhance freshness and hygiene and minimize unpleasant odors. Supplied in masterbatches, nShield® antimicrobial polymers can be employed across a wide range of synthetic fiber applications, including textiles and nonwovens, as well as various plastics articles.

Americhem’s nShield® is a broad-spectrum antibacterial agent that provides proven action against Gram-positive and Gram-negative bacteria. We can design products that achieve up to Log 3 (99.9%) and Log 4 (99.99%) reduction standards by altering nShield® concentrations in certain polymer systems.


Developed with broad processing capabilities in mind, nShield® is compatible with most melt-processed polymers. These high-performance additives are available in various inorganic and organic materials with suitability that’s dependent on the polymer system and the processing temperature. Our silver-based formulations are widely used due to their antibacterial effectiveness, durability and controlled ion release, but Americhem offers a wide range of formulations to meet a variety of specifications. Americhem’s material science experts will work with you to determine any regulatory requirements for material ingredients and tailor an agent to achieve proper oxidation, efficacy and duration.


Americhem’s team of qualified chemists undertake a 360-degree view of your product’s application and the environment in which it must perform. We are continuously studying additive and polymer interactions and building upon our knowledge of end-use articles containing antimicrobials. Leveraging our unrivaled experience in functional technology and nonwoven fibers additive solutions, we are able to create custom antimicrobial formulations to ensure all design criteria are met. While we never take a one-size-fits-all approach, we have developed some off-the-shelf products based on our industry experience. Having a complete line of nShield® antimicrobial additives creates greater efficiencies and attractive price points for our customers. Finally, we use industry standard tests to confirm valuations and specially developed dispersion characterization techniques to evaluate performance.


You will find nShield® antimicrobial additives in many of the world’s most respected product brands. In hospitals and healthcare facilities, nShield® can be integrated into face masks, other personal protection equipment (PPE), bedding, sheets and curtains to reduce bacterial growth. Personal hygiene products like diapers and adult incontinence wear that can benefit from enhanced freshness and odor control can also be modified with Americhem’s softening agents to achieve value-added comfort. Beyond healthcare and hygiene applications, our innovative antimicrobial additives for synthetic fibers can make synthetic turf, floor coverings, performance apparel and hosiery more resistant to the effects of microbe growth. And our antimicrobial uses are always expanding!
