A new collection of highly aromatic multi-functional polyols from Hexion could provide a range of useful properties in rigid polyurethane and PIR applications
The ability to mix and match polyols and diisocyanates allows polyurethane materials to be created with a versatile range of properties. Hexion has recently introduced a range of highly aromatic polyether polyols that can give useful performance advantages in rigid polyurethane and PIR applications.
This paper concentrates on the evaluation of two different polyol replacements, one in rigid PU applications and the second in spray foams. In both cases, the substitutions can produce formulations with a significant improvement in and flammability performance. There was a compressive strength improvement in the rigid formulation too. The foams produced in this work burnt significantly more slowly than the formulations they were compared with. It is possible that using Resonance polyols could simplify formulations by reducing the amount of fire retardant needed to meet standards.
