HFC365mfc/245fa blend Applications

HFC 365mfc/HFC 245fa blend is the perfect balance of characteristics of both third generation blowing agents HFC 365mfc and HFC 245fa. A zero ODP HFC blend (as an R-141B replacement). Good thermal conductivity. Converting foaming machines from HCFC-141b to HFC-365mfc/245fa is easy and cost effective. 365/245 gives superior insulation performance, excellent fire resistance, easy processing. Existing Storage Facilities can be used, Some precautions are recommended to account for potential flammable mixtures in air (e.g. no smoking policy etc.) – no ex-proof facility is required. Applications include reefer containers and refrigerated transportation, continuous/ discontinuous insulation panels, sandwich panels, appliances.
