Forane® 365mfc

Forane® HFC-365mfc, 1,1,1,3,3-pentafluorobutane, and Forane® 365HX (a blend of HFC- 365mfc and HFC-4310mee ( 1,1,1,2,2,3,4,5,5,5-decafluoropentane)), are liquid, SNAP approved HFC solvents available through Arkema for use as components in solvent blends to replace HCFC-141b in precision cleaning, electronics cleaning, and carrier applications.

Forane® 365HX is a non-flammable blend, patented by Arkema.

Advantages of using Forane® HFC-365mfc and Forane® 365HX:

• Compatible with most metals, plastics, and elastomers
• Good co-solvent
• EPA SNAP approved for solvent use
• Low toxicity
• Environmental Profile: Non-VOC, Zero ODP, Low GWP
• Low cost relative to other commercially available solvent alternatives
  

Impact on Environment

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

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

Forane® HFC-365mfc and Forane® 365 HX have low toxicity and are not listed as Volatile Organic Compounds (VOCs). They have been specifically exempted by the EPA from VOC Regulations because of their 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.
