Antimicrobial for Polymers and Resins
The 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
The antimicrobial can be added to a variety of polymers (e.g. vinyl, rubber, latex, PP, PS, ABS) that are found in a variety of consumer products and can be easily molded or extruded as part of the manufacturing process.
Incorporating antimicrobial protection into your bath products, kitchen products, appliances, and food storage containers will serve to prevent product deterioration, stains, unpleasant odors and bacteria due to microbial presence.
The commercial and foodservice industries are breeding grounds for odor, stain causing bacteria.
From aircraft interiors to commercial high chairs to food processing materials, the additive offers product protection on items such as plastic foodservice transportation bins, TV remote controls and other polymer-based containers and products.
The Case for Polymers
Our controlled release antimicrobial system is one of the few that can survive extrusion/molding temperatures:
Our particles are thermally stable, 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 nanoparticle, it should improve the mechanical properties of polymers.
As a nanoparticle, it will blend better with polymer, creating a more uniform distribution; and,
Lastly, the surface of our nanoparticle can be made hydrophilic or hydrophobic depending on the polymer system of interest.
Our controlled release antimicrobial is effective against gram positive, gram negative bacteria (including methicillin-and vancomycin resistant bacteria) as well as fungi and viruses.
With significantly higher potency, it requires lower antimicrobial dosages with a lower environmental footprint and lower non-bacterial cellular interactions. The key features of our antimicrobial are:
- An enormous increase in surface area, resulting in more coverage with lesser particle amounts. Compared to micron-sized particles that is an 1000x increase in surface area coverage.
- 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.
