Susterra® Propanediol

1,3, propanediol. It is petroleum-free, environmentally sustainable and is certified by the USDA as 100% bio based. 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. Used in urethanes for microcellular elastomers, thermoplastic polyurethanes, and aqueous polyurethane dispersions. Also used in downstream markets include footwear, and wheels and casters. Can be used as the glycol portion in the manufacture of unsaturated polyester resins that are further used in the construction, marine and automotive industry worldwide with end users that require high performance polymers with a more sustainable footprint.

Hansen Solubility Parameters

[17.4, 23.7, 11.7]
?
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Susterra® Propanediol. A practical determination of these HSP values would provide higher certainty. Learn More.
