Thermal Decomposition Model Development of EN-7 and EN-8 Polyurethane Elastomers.

Thermogravimetric analysis - gas chromatography/mass spectrometry (TGA- GC/MS) experiments were performed on EN-7 and EN-8, analyzed, and reported in [1] . This SAND report derives and describes pyrolytic thermal decomposition models for use in predicting the responses of EN-7 and EN-8 in an abnormal thermal environment.

Additive Manufacturing of Polyurethane Foam Mold Tooling

In this DOE AMO Technical Collaboration (MDF-TC-2017-078), ORNL partnered with Whirlpool Corporation. to develop low-cost prototype tooling for the manufacturing of refrigerators. Techniques for producing watertight and high thermal-conductivity tools were developed and evaluated. In addition, additive manufacturing systems at multiple volume and resolution scales were evaluated for performance, resolution, and cost for the intended application.
