SOLKANE-Insulation-iconSOLKANE® 365 is a hydrofluorocarbon of the latest generation. It has no ozone depleting potential and with its boiling point of 40 °C it can be handled as a true liquid at room temperature. It is a colourless, compound with a faintly ethereal odour, used for a wide range of applications within PU foams, solvents or heat transfer fluids.

The chemical stability of SOLKANE® 365 is even better when compared to HCFC 141b. Therefore no stabilizer is needed if SOLKANE® 365 is stored under appropriate conditions (for details please refer to our SDS).

SOLKANE® 365 is a perfect team player. It is miscible with a wide range of other organic foam blowing agents like other HFCs or even hydrocarbons.

The choices are up to you and almost unlimited. Blending of i.e. cyclopentane with SOLKANE® 365 strongly improves the lambda value while reducing the density of the resulting PU foam. That means, running SOLKANE® 365 in your system minimizes raw material costs while improving insulation performance. That is what we call a win win situation!

SOLKANE® 365 is your first choice when fire safety is demanded. Fire classifications and fire performance tests are of increased importance for modern PU products especially in the building industry. Combined with the Solvay's IXOL® range of reactive flame retardant polyols, SOLKANE® 365 blown PU foams reach the highest possible classifications for organic insulation materials.
