Emission and Extraction Study

Emission and Extraction Study

The PMA has commissioned EHS Analytics to perform emissions and extraction testing of the following potential residual compounds in hot cast/heat cured polyurethane elastomers: TDI, TDA, MDI, MDA and MOCA. TDA (toluene diamine) and MDA (methylene diphenyl diamine) are included in this study because they are the hydrolysis by products of TDI and MDI, respectively.

This project commenced in October 2020 and was completed in Spring 2021.
