  • Susterra® provides low toxicity, safety, and is readily biodegradable

ASTM Approval

DuPont Tate & Lyle Bio Products is excited to announce that 1,3-Propanediol (PDO) has been approved by the ASTM International Committee D15 on Engine Coolants for use as an Engine Coolant Base. This approval offers coolant manufacturers and suppliers an alternative glycol coolant base that functions effectively to provide protection against freezing, boiling, corrosion, and cavitation.

PDO based coolants can offer prevention from premature coolant degradation, lower maintenance and lower lifetime cost technologies for cooling systems, and better oxidation resistance than traditional glycols. The main users of these standards would be engine coolant manufacturers and their customers, mechanical engineering contractors and suppliers of power generation and emergency power generation systems.

The approval process included four ASTM standards which are available via the ASTM Website. Read Press Release
