To help manufacturers address one of the main issues with recycled plastics, unpleasant odors, Struktol Company of America has introduced two new odor-control additives, RP 17 and RP 53. By masking and eliminating lingering smells, these solutions increase the appeal of recycled materials for high-end applications. Struktol is putting itself at the forefront of polymer innovation by fusing performance and sustainability.

The first product, RP 17, is primarily a masking agent that improves the sensory profile of plastics, especially those with high recycled content. On the other hand, RP 53 takes odor management a step further by actively neutralizing compounds such as amines, phosphates, and mercaptans, which are typically difficult to control. This dual-action approach offers manufacturers flexible options, depending on the severity of odor issues in their production streams.

The formulation of both additives allows for seamless integration into post-industrial and post-consumer recycled grades of polypropylene (PP) and polyethylene (PE) systems. Because they only need a small dosage, typically 0–5% to 3 percent, processors can improve the quality of their odors without making major changes to their formulations. Along with improving odor, these additives accelerate mixing, enhance dispersion, and prevent equipment buildup, all of which enhance processing.

Struktol has also designed these products with practical handling in mind. RP 17 and RP 53 are low-dust formulations available in a variety of packaging sizes, from 25-kilogram bags to large industrial skids, making them adaptable for different-scale operations. Their stable shelf life of up to two years ensures reliability and long-term usability for processors.

These new additives arrive at the perfect time, as the plastics industry is under pressure to increase recycled content without compromising product quality. With Struktols' invention, manufacturers can produce sustainable goods without sacrificing consumer acceptance by using material science to overcome the sensory difficulties associated with recycling. In the pursuit of cleaner, more sustainable polymers, RP 17 and RP 53 mark a breakthrough by addressing both odor control and processing efficiency.
