What is zeolite and what are the applications?

Zeolite is a group of microporous, crystalline aluminosilicate materials, balanced with cations. Conventional zeolites are commonly used as commercial adsorbents and catalysts.

What is the difference between conventional zeolite and the colloidal zeolite?

Conventional zeolites are usually in micron size. Colloidal zeolite refers to the zeolite particles which is able to uniformly and stably float in water to form suspensions. Colloidal zeolite usually has particle sizes smaller than 100 nm.

What is the unique feature of the colloidal zeolite based antimicrobial additive?

The zeolite additive is constituted of internal holes/cages, suitable for encapsulating cations and molecules. Functionalities can be designed either by purposely filling these holes with appropriate active molecules/ions or the empty cages can be used to remove ions/molecules from the environment. These colorless, odorless, almost invisible additives can be delivered as sprays, surface coatings and can be incorporated into polymers and textiles with different form factors.

What zeolite consulting and collaboration services does ZeoVation provide?

The R&D team at ZeoVation has strong zeolite R&D background. The CTO of ZeoVation is retired Distinguished Professor at The Ohio State University with more than 40 years of R&D experience on zeolites. The CEO of ZeoVation has more than 10 years experience on zeolite research and commercialization. At ZeoVation, we provide consulting services and partnership in zeolite related product development projects..

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.
