Fluorocarbons & Sulphur Hexafluoride and Insulation Foams

Several HFCs have excellent thermal insulating characteristics. These specific properties have made them good candidates as foam-blowing agents for the replacement of HCFC-141b and HCFC-142b in the production of insulating foam.

This is particularly the case in those applications where there is limited space available for insulation, e.g. appliances such as freezers and refrigerators. The use of HFCs enables appliance manufacturers to meet stricter energy-consumption standards while offering their customers the same storage capacity.

Because of their favourable toxicity and flamability properties, these HFCs are also the foam blowing agent of choice in in-situ insulation. They help the owners of many older buildings to achieve lower heating and cooling expenses.

At the same time, the use of these HFCs in providing superior insulation is reducing CO2 -emissions associated with the energy required for the heating and cooling.
