Wax Temperature & Processing
A) Does anyone know why the manufacturers of the histological paraffin
waxes(eg Paraplast) put a warning on the package not to heat the contents
I have heard reports of the following but have not witnessed:
1. Polymers precipitating from the molten paraffin above this temperature
limit which changes the physical properties (increases melting point, makes
wax softer and hence blocks are harder to cut... )
2. There might be toxic additives that are released above this
temperature.(although not specifically addressed in the MSDS).
Is this correct or are there other reasons?
Thanks in advance,
