Bio-Bases Millathane GradesMillathane is advancing its commitment to sustainability by offering a more environmentally friendly alternative to traditional polyurethane polymers. While the standard Millathane polymers use fossil-based raw materials, the new bio-based Millathane polymers provide similar performance with a reduced environmental impact.

Our eco-friendly Millathane polymers utilize polyols derived from non-food plant crops, marking a shift towards renewable resources.  To date, we’ve successfully developed three bio-based grades that closely mirror the physical properties of our standard Millathane E34, Millathane 55, and Millathane 26 polymers. These eco-friendly alternatives boast impressive bio-content percentages: 85% for bio-based Millathane E34, 77% for Millathane 55, and 87% for Millathane 26.

In typical test formulations, bio-based Millathane polymers performed similarly to, and in some ways better than, traditional ones.  When compared to standard Millathane polymers, they exhibit lower hardness at the same filler loading, higher elongation at break, improved low-temperature properties, and slightly better compression set resistance.  These enhancements, combined with their renewable origins, make our bio-based Millathane polymers an excellent choice for environmentally conscious manufacturers seeking high-performance materials.
