  • Material make-up

    0% harsh chemicals, mineral acids, catalysts.

  • Key takeaway

    Significant enhancement of elongation and reduction of brittleness.


Our journey began with in-depth discussions with our confidential client to understand their specific needs and sustainability goals. Leveraging our expertise in sustainable additives, we developed erthos® Plasticizer, a bio-based alternative to ESO, tailored to meet the client's requirements. Through rigorous testing and optimization, we ensured that the additive enhanced the flexibility and durability of the client's materials while reducing their environmental footprint. We then supported the client in integrating Erthos® Plasticizer into their manufacturing process seamlessly, providing ongoing technical assistance to ensure a smooth transition.
