Hello all. I have a few questions regarding the starting materials for PUR foam manufacture.
In a generic formulation of TDI and polyol:
Will the temperature of the chemicals prior to mixing have an impact on the reaction? How? What will be the impact?
I understand that the freezing point of TDI is fairly low. How would it be affected if it froze in transit? Chemically, would there be any difference? Would there be any disassociation of components?
Is there a in-situ method for monitoring the reaction of these 2 components?
I'm considering the use of CO2 as a blowing agent. The CO2 will be mixed with the polyol, then fed into a mix head with the TDI. Are there any special precautions needed for this?
This chemistry is new to me and these will probably be the first of many qeustions. Thanks very much for any insight anyone can provide.
