Impact on Environment

Compared to HCFC-141b, Forane HFC-365mfc is more environmentally friendly. The following table compares the Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) of HCFC-141b and HFC-365mfc.

	HCFH-141b	HFC-365mfc
Ozone Depletion Potential (ODP)	0.11	0
Global Warming Potential (GWP) (Time Horizon - 100 years)	630	910

* The individual components, HFC-365mfc and HFC-4310mee, have a GWP of 910 and 1300 respectively.

Forane HFC-365mfc has low toxicity and is not listed as Volatile Organic Compounds (VOCs). It has been specifically exempted by the EPA from VOC Regulations because of its negligible photochemical reactivity. Forane HFC-365mfc is listed on the TSCA inventory. HFC-4310mee (1,1,1,2,2,3,4,5,5,5-Decafluoropentane, CAS# 138495-42-8) is controlled by TSCA, Section 5, Significant New Use Rule (SNUR; 40 CFR 721.5645). The approved uses are:  Precision and general cleaning, carrier fluid, displacement drying, printed circuit board cleaning, particulate removal and film cleaning, process medium, heat transfer fluid (dielectric and non-dielectric), and test fluid. Processors and users of this substance must also comply with the applicable general SNUR requirements set forth in 40 CFR 721 subpart A, including export notification requirements if applicable (40 CFR 721.20), and the applicable record keeping requirements set forth at 40 CFR 721.125.
