The Polyurethane Foams Based on Melamine-formaldehyde-cyclohexanone Resins
Keyword(s):
The conditions and methods for obtaining polyurethane foams based on melamine-formaldehyde-cyclohexanone resins are presented These foams were obtained from melamine solution in reactive solvents based on cyclohexanone and 4,4′-diphenylmethane diisocyanate. Some properties of obtained polyurethane foams were examined, e.g. apparent density, water absorbing capacity, dimensional stability, thermal conductivity, thermal stability, flammability and compression strength. Also a thermal analysis using the differential thermal analysis and differential scanning calorimetry methods was carried out. Polyurethane foams with increased thermal stability were obtained.
