PUBLISHED EVIDENCE SUPPORTS VERY LOW YIELDS OF TFA FROM MOST HFOs AND HCFOs
EFCTC has analysed the most current, peer reviewed scientific papers on the potential contribution of HFOs and HCFOs, containing the CF3CH= moiety, to existing and future TFA levels. The conclusion from these papers is that the very low yields of TFA from these substances mean that their expected contribution to TFA in the…
