In today’s world, recycled plastics and rubber are more important than ever. But let’s face it—unpleasant odors are one of the biggest barriers to consumer acceptance and wider adoption. Whether in packaging, automotive interiors, or household goods, no one wants the smell of sulfur or burnt residues in their hands.
That’s where Termoform’s POLYNOR® DF Series steps in. Instead of masking smells with fragrances, DF works at the molecular level to neutralize odor-causing compounds permanently. This means products don’t just smell better—they are better.
The Challenge
Recycled plastics and rubber are increasingly used in high-performance applications. Yet, they often carry strong, undesirable odors from prior use or chemical degradation. Traditional fragrance-based solutions only hide these odors temporarily, and they fade quickly in high-temperature processing. Manufacturers have been looking for a solution that’s permanent, efficient, and reliable.
The Innovation
POLYNOR® DF Series was developed to directly tackle this problem. Its inorganic carriers with micro-porous structures and functional low-molecular-weight components capture and neutralize nitrogen (amino) and sulfur (mercaptan) odors. Even at elevated processing temperatures, DF retains its effectiveness.
The series comes in two specialized forms:
-
POLYNOR® DF 25 Masterbatch – For plastics such as PE, PP, EVA, PVC, and HIPS.
-
POLYNOR® DF 25 Powder – Specifically engineered for rubber applications like footwear, mats, gaskets, and molded parts.
Both solutions are designed to integrate seamlessly into compounding, offering high compatibility and easy processing.
Applications Across Industries
POLYNOR® DF 25 is already improving product quality across sectors:
-
Blown Film & Sheets: Keeps packaging odor-free while maintaining clarity and mechanical properties.
-
Recycling: Enables higher recycled content without compromising consumer appeal.
-
Injection Molding: Enhances sensory characteristics in automotive components, household items, and industrial parts.
-
Rubber Goods: Eliminates sulfuric odors in footwear, seals, and mats.
Why It Matters
For manufacturers, POLYNOR® DF doesn’t just mean odor-free materials—it means:
-
Greater freedom to use recycled content.
-
Improved consumer trust and product marketability.
-
Enhanced competitiveness in industries demanding both sustainability and performance.
The Result
With POLYNOR® DF Series, Termoform is helping manufacturers cross the odor barrier and unlock the full potential of recycled plastics and rubber. It’s a small additive with a big impact—turning challenges into opportunities and keeping sustainability at the forefront of innovation.
