Susterra^™ propanediol is a specialty glycol that offers a non-petroleum alternative for end uses that desire a bio-based product—without sacrificing performance or quality.

Susterra^™ propanediol can be used in applications such as deicing and heat transfer fluids and as a base for engine coolants where stability over a range of temperatures is important.

In polymer applications, Susterra^™ propanediol can be utilized in the manufacture of polyester-based resins and as a cross linker in urethane chemistries. DuPont^™ Sorona^® and DuPont^™ Cerenol^™ are two new products that utilize the unique properties of Susterra^™ propanediol. They are currently being used in a wide variety of segments such as automotive, engineering polymers, fibers and coatings.

Benefits:

In deicing applications, 100% renewably sourced Susterra^™ propanediol provides low toxicity and biodegradability.

Susterra^™ propanediol delivers excellent freeze point depression for aqueous solution applications that require freeze protection.

In anti-freeze applications, Susterra^™ propanediol provides improved heat stability and less corrosion than other propylene glycol and ethylene glycol formulations, resulting in longer life for today’s high-performance engines.

Resins made with Susterra^™ propanediol feature improved flexibility and impact resistance.
