Susterra® Propanediol

When performance matters, choose Susterra® propanediol—the pure, bio-based, petroleum-free diol. Susterra® propanediol is the building block that delivers high performance in a variety of applications, from polyurethanes and unsaturated polyester resins to heat-transfer fluids.

For polyurethanes, Susterra® propanediol is an excellent polyol or chain extender that gives manufacturers flexibility when developing high-performing, bio-based solutions.

As the primary ingredient in heat-transfer fluids, Susterra® propanediol functions as a higher-performing, food-safe glycol for process heating and cooling. Susterra® propanediol has unique performance advantages: it can directly replace propylene glycol yet provides fluid manufacturers with improved performance at both high and low temperatures.

Susterra® propanediol benefits include:

  • Pure
  • Petroleum-free
  • Non-toxic and food safe
  • 100% sustainably and renewably sourced
  • USDA 100% certified bio-based product

Plus, Susterra® propanediol is renewably sourced and generates up to 50% less greenhouse gas emissions over its life. Susterra® propanediol can help companies fulfill their sustainably goals without compromising on quality across a variety of industrial applications, including:
