What Is an Antimicrobial Plastic?

An antimicrobial plastic is a synthetic polymer material containing an integrated active ingredient which makes it effective against microbial growth.

Create High-Performing Antimicrobial Plastic Products with Microban®

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

Adding Antimicrobial Agents to Plastics

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.

Common Applications for Antimicrobial Plastic Additives

Microban® technologies are implemented by plastic product manufacturers around the globe, in a variety of different industries. Consumer, commercial, healthcare and building products all benefit from the added layer of protection provided by our portfolio of solutions.
