| Abstract: | Monitoring and evalution of exotherms as temperature rises were investigated using
various foam formulations from two types of polyols with variations in blow indices as
volume of water added. It was observed that exotherms increase linearly with blow index.
The results also showed that density variations are in inverse relationship with the
exotherms, foam heights and compression sets. Furthermore, it was similarly observed
that as the blow index increases, ΔT1 and ΔT2 increase for both conventional (CPO) and
polymer (PPO) polyols far above the acceptable temperature range of 22-26ºC for foam
manufacture with consequences on physical properties. |
