Antimicrobial Plastics & Polymers

Microban® antimicrobial plastic additives can be manufactured into a range of polymers to inhibit the growth of bacteria, mold and mildew on the surface of the product.

Microban is widely recognized as the world leader in built-in antimicrobial technologies. Our portfolio of antimicrobial additives helps keep polymer products and surfaces cleaner by inhibiting the growth of bacteria, mold, and mildew. Microban's customized chemistries are incorporated into plastic products at the point of manufacture and provide ongoing protection for the expected lifetime of the product.

What Is the Key Difference Between Plastics and Polymers?

In simple terms, all plastics are polymers but not all polymers are plastics. Polymers can exist organically or be created synthetically. They consist of chains of joined individual molecules or monomers. By contrast, plastics are composed of chains of polymers that can be partially organic or fully synthetic.

Polymers are classed into two categories: thermosetting polymers, and thermoplastic polymers.

Thermosetting Polymers
Also called ‘thermosets,’ these polymers become permanently rigid when heated, bonded by a physical crosslink. They cannot be melted down to be reshaped or reformed. Thermosets include items like silicone seals, window gaskets, epoxy resins, or polyurethane foams.
Thermoplastic Polymers
Thermoplastic polymers can be heated and cooled over and over to change their shape, becoming pliable under a certain heat level, and then solidifying when cooled. Thermoplastic polymers include polyethylene, polypropylene, epoxy, and polyester, making up items like plastic bags, water bottles, and food containers.

What Is an Antimicrobial Polymer?

Antimicrobial polymers are lightweight, strong substrates treated with an antimicrobial additive that becomes a permanent part of the material, making it inherently resistant to the growth of microbes.

Create High-Performing Antimicrobial Plastic Products with Microban®

Microban has over 25 approved antimicrobial technologies that can be formulated into polymer pellets, powders, or liquids. For injection molded or extruded thermoplastic polymers, an extensive set of specialized pellet-based masterbatches are available to ensure seamless incorporation. These masterbatches are designed to be used in a manner similar to color masterbatches and are safe to handle, accurate to add via a variety of methods, and fully compatible with your manufacturing method and material without requiring process changes.

Microban also offers a variety of powder and liquid-based masterbatches for other processes such as powder coating, reaction injection molding, cross-linked liquid applied coatings, roto-molding, and foaming. All of our antimicrobial technologies for plastics can be integrated without affecting gloss or matte surfaces, color, durability, and resistance to cleaning solvents.

The world-class research & development team at Microban includes experienced polymer engineers who work directly with partners to identify the best antimicrobial agents for their plastic products. More than 30,000 tests are conducted annually at our state-of-the-art laboratory facilities and our team stands behind the efficacy of each application.

Microban antimicrobial additives are customized to our partners’ unique applications and environments. Our technologies are primarily comprised of Silver Ion and Zinc to achieve antibacterial and antifungal efficacy, respectively, to give end-users greater peace of mind and offer products that contribute to a systems approach to clean.
