ABSTRACT
HFC-365mfc is a key for promising blends. A new blend Solkane® 365/227 meets best the main requirements as a substitute for HCFC-141b: Solkane® 365/227 is a non-flammable liquid, starts boiling around 30°C and has all the advantageous properties of HFC-365mfc. Different to HCFC-141b it is a binary blend and must be handled adequately to maintain the non-flammable character.
Several hundreds of tons of Solkane® 365mfc have been produced since January 2000 in a pilot plant. This enabled the foam industry to start the optimization of their systems.
A limited amount of blowing agent can give the best foam insulation performance at low temperatures and can save costs. Rules assist the producers to develop quality and cost effective formulations when replacing HCFC-141b with HFC-365mfc-blends.
