Antimicrobial Plastic & Polymers 

The antimicrobial polymer additive is an advanced controlled release antimicrobial treatment for polymers and resins. It keeps products made from polymers and resins free from dangerous bacteria while maintaining polymer durability and integrity.

Markets We Serve 

Consumer Products

The antimicrobial plastic additives can be added to various polymers (e.g., vinyl, rubber, latex, PP, PS, ABS) found in various consumer products and can be easily molded or extruded as part of the manufacturing process.

Incorporating antimicrobial additives protection into your bath products, kitchen products, appliances, and food storage containers will prevent product deterioration, stains, unpleasant odors, and bacteria due to microbial presence.

Commercial Products

The commercial and food service industries are breeding grounds for odor-stain-causing bacteria.

The additive offers product protection on plastic food service transportation bins, TV remote controls, and other polymer-based containers and products from aircraft interiors to commercial high chairs to food processing materials.

What are the Benefits of the Antimicrobial for Plastics & Polymers?

Our controlled release antimicrobial polymer additive system is one of the few that can survive extrusion/molding temperatures:

  • Our thermally stable particles and our anti-microbial can be processed at high temperatures.
  • It is a colloidal suspension, and particles in this form do not settle, so it will mix better with a polymer system before processing (extrusion)
  • As a colloidal particle, it should improve the mechanical properties of polymers
  • As a colloidal particle, it will blend better with polymer, creating a more uniform distribution
  • The surface of our colloidal particle can be made hydrophilic or hydrophobic depending on the polymer system of interest

The Effectiveness 

Our controlled release antimicrobial is effective against gram-positive, gram-negative bacteria (including methicillin- and vancomycin-resistant bacteria), fungi, and viruses. 

With significantly higher potency, it requires lower antimicrobial dosages, a lower environmental footprint, and lower non-bacterial cellular interactions. The key features of our antimicrobial are:

  • An enormous increase in surface area results in more coverage with lesser particle amounts. That is a 1000x increase in surface area coverage compared to micron-sized particles.
  • Faster, more efficient ion exchange due to the shorter distance the molecules have to travel 
  • Ability to penetrate and destroy bacteria from the inside out.
