Performance polymers

Clearly better

Susterra® propanediol is the plant-based building block that delivers high performance across a wide variety of polyurethane applications. It is an excellent polyol or chain extender for the manufacture of urethanes. Depending on the chemistry selected, the urethane’s structural block can yield a final product with enhanced mechanical properties.

The performance benefits of Susterra® propanediol include:

  • Improved flexibility and tear strength
  • Outstanding resilience
  • Excellent adhesion
  • Softness and transparency
  • Enhanced abrasion resistance
  • 100% USDA bio-based material, renewably and sustainably sourced

Susterra® propanediol is effective in the following industrial polyurethane applications:
