Drying before processing is highly recommended : moisture content should be a maximum of 0.2%.
The maximum permissible drying temperature lie in the range of about 80-1100 C
PA 6,6 is thermally
stable up to 3100 C, but above decomposition accelerates, the initial
products formed being mainly carbon monoxide and ammonia, and
caprolactam.
