Scentry™ for Polymers

The Problem

Recycled-content plastics have a tendency to smell due to previous product use; they can have entrained organic materials that eventually emit an unpleasant odor. These odors often develop during processing and linger through to a finished product. Microban has developed a line of non-antimicrobial odor control products to address these production issues. Scentry® for Polymers additives are pellet-based concentrates added to a recycle polymer stream during compounding that neutralize material odors before they are incorporated into consumer and commercial goods. Production conditions during processing will often also improve. Scentry® technology is nontoxic and safe for humans, animals and the environment.

The Solution

Scentry® technology uses active particles that contain billions of micro and nano-pores that absorb and trap odor molecules permanently. Since the specific odors countered by any given active depends on the pore size distribution of that material, Scentry® actives employ a broad spectrum of pore sizes allowing them to trap a broad range of odors as seen in the figure below. As an added benefit, Scentry® technology can reduce odors produced by off gassing during the manufacturing process, helping to create a safer work environment. Further, depending on the manufacturer’s specific needs, Scentry® for Polymers additives can be custom designed by Microban to be dual-functioning, combining odor capture and an antimicrobial to help fight against stain-and odor-causing bacteria and product degradation.

How Scentry® is Implemented

Scentry® for Polymers is effective in wide variety of categories, including trash cans, flooring, camping accessories, outdoor storage, camping furniture, footwear and electronic cases, just to name a few. Not just a single product, Scentry® for Polymers formulations can be customized to thwart a variety of specific odors, and is available in light and dark (black) versions. Addition rates will depend strongly on the strength of the problem odor and the desired degree of control, but are typically in the 0.5% to 3% range.
