WithStand™ Antimicrobial Technology

Let’s face it – germs are everywhere, especially on tactile communicating polymer surfaces. Whether your customers are consumers, food and beverage manufacturers, hospitals, or patients, you want to be able to combat surface microbe formation and growth on your product’s plastic surfaces. Our material science knowledge and efficacy experience formulating with almost every polymer that exists on the planet, our WithStand™ Antimicrobial Technology provides a proven, effective, durable, uncompromised solution to limit microbe development in finished plastic devices. It also helps to reduce odor, staining, discoloration, loss of mechanical properties and other detrimental effects of microbe growth.


Our customers select WithStand antimicrobial and antifungal additives to enhance the performance and value of the products and devices they supply to the consumer, food, cosmetic, health and wellness industries in the following ways:

  • Increased Speed to Market: By providing a “one stop” solution to reduce microbe growth, the WithStand Antimicrobial Technology portfolio and service can help customers address microbial problems quickly and effectively.
