Repel Fluids. Meet Compliance. Drive Sustainability.

Global PFAS regulation is accelerating, and OEMs must transition to polymer‑level PFAS‑free solutions that maintain performance across diverse fiber systems.

nDryve™ provides PFAS- and PFOA-free, in‑melt fluid repellency designed for fiber and nonwoven systems. It resists alcohol and other low‑surface‑energy fluids, including water, oils, and challenging contaminants encountered in real‑world use.

Unlike topical finishes, nDryve™ is incorporated during melt processing, embedding fluid repellency directly into the fiber matrix. This enables repeatable performance, fewer processing steps, and reduced chemical handling—all while delivering durable resistance to alcohol and other low‑surface‑energy fluids.

  • PFAS/PFOS-Free formulation for global compliance
  • Multi-fluid protection: alcohol, water, and oils
  • Stain resistance for cleaner, longer-lasting fabrics
  • Easy integration into high-speed lines
  • Compatible with PP, PET, and PA6

Engineered for the PFAS Transition, Without Compromising Performance

Designing PFAS-Free Repellency in Fiber Systems

nDryve™ is designed as an in-melt technology platform and is implemented during polymer melt and fiber formation.

It is not a topical finishing treatment applied during dyeing or post-processing. The performance is engineered directly into the fiber structure, which supports durability under repeated exposure and reduces reliance on surface-applied chemistries.

For textile converters working downstream, collaboration typically involves working with fiber manufacturers to integrate the technology at the fiber stage.

Yes. Within the nDryve™ technology platform, different PFAS-free chemistries are developed depending on the specific fluid interaction requirement. Alcohol repellency, hydrophobic performance, stain resistance, and oleophobic challenges involve different polymer fluid interactions.

Rather than relying on a single chemistry, nDryve™ uses application specific in-melt formulations engineered for the targeted performance and polymer system. Oleophobic performance presents a higher technical challenge compared to hydrophobicity, and development is approached accordingly within the same PFAS-free, in-melt design framework.

Yes. Polymer chemistry significantly influences performance.

Polyolefins (e.g., PP) differ in polarity and crystallinity from engineering polymers such as PET or PA6. These differences affect additive dispersion, migration behavior, and overall fluid interaction.

As a result, optimized formulations are developed for polyolefin and engineering fiber systems, including PET and PA6. The core design principle is PFAS-free, in-melt integration remains consistent, but the chemistry is tailored to the polymer and end-use requirements.

nDryve™ is not based on a single chemistry and does not rely on PFAS.

Different PFAS-free chemistries are used within the platform depending on the target performance (e.g., alcohol repellency, hydrophobic performance, stain resistance).

Regarding mechanical properties, formulations are designed to maintain fiber processability and functional integrity. As with any additive system, loading level and polymer compatibility are important considerations.

From a recyclability standpoint, because the additive is integrated at typical in-melt loading levels and does not introduce fluorinated chemistry, the impact on end-of-life processing is generally more manageable than traditional PFAS-based systems. Specific evaluations depend on polymer type and recycling stream.

Loading levels depend on the target performance requirement, polymer system, and processing conditions.

For hydrophobic performance in PP fibers, relatively low in-melt loadings may be sufficient. More demanding multi-fluid repellency targets may require higher optimization.

Rather than using a one-size-fits-all loading, development typically involves collaboration to balance performance, processability, mechanical properties, and cost targets within the specific fiber application.
