The last post in our Microban Antimicrobial Blog Series helps to clarify the differences between the various microoganisms around us.  Again, a big THANK YOU to the team at Microban for providing us with additional information on their testing proceedures and how they work to provide PORON® Cushioning Materials with continuous antimicrobial protection!

As always, if we haven’t answered all your questions, please post them below and we’ll be sure to get back to you!

Antimicrobials 101

Consumers around the world are recognizing a growing need for bacterial and mold control in products used every day. This need stems from an estimated 4.5 million bacterial and fungal species living throughout the planet.   The majority of these microorganisms do not cause a concern for human health, or even the life span of a product for that matter.  However there are some that are problematic, which can be found in our everyday activities.

What’s a Microbe?

Microbes or microorganisms are living cells that are too small to be seen with the naked eye and must be viewed through a microscope.  The naked eye is only able to detect the presence of microbes once they have multiplied to the hundreds of thousands.  Types of microorganisms include bacteria, algae and fungi or mold.

*Microban® antimicrobial product protection is engineered to protect products from bacteria, mold and mildew that can cause stains, odors and product deterioration. Microban protection is not designed to protect users from disease causing microorganisms.


Billions of years ago, bacteria were among the earliest forms of life on Earth. There’s no escaping the presence of bacteria and in fact, many of the bacteria we encounter are beneficial to the environment and even to the human body, helping us to digest food for example. However, some bacteria such as those causing stains, odors and/or product deterioration can adversely affect the everyday products we use every day.


Early fossil records suggest that fungi have been on Earth for over 550 million years; some experts estimate that today over 1.5 million fungus species exist. Common fungi include mushrooms, puffballs, truffles, yeasts and most mildews.

Mold spores are present everywhere in our indoor and outdoor environment and many of the products found in our homes provide rich nutrient sources. The best defense is prevention: control moisture in your home to avoid high humidity levels and look for products that resist the growth of mold.

Why Microban® Protection for PORON® Cushioning Materials?

Microbes such as odor and stain causing bacteria, mold and mildew can quickly multiply on surfaces.  In fact, on an unprotected surface, bacteria can double in number every 20 minutes!  Warm moist environments found in places such as shoes, protective apparel and equipment provide favorable conditions for the growth of odor and stain causing bacteria, mold and mildew.

This is why Rogers Corporation has teamed up with Microban, the global leader in built-in antimicrobials, to provide continuous antimicrobial protection in their PORON® Cushioning Materials that is often used in footwear, protective apparel/equipment and outdoor equipment.

Microban® antimicrobial technology is incorporated into PORON® cushioning products during the manufacturing process to inhibit the growth of stain and odor causing bacteria, mold and mildew that can accumulate on the foam.  Microban protection works 24/7 to help keep the cushion cleaner and fresher for longer than ever before.
