Q

PA12 Silver Streak from Insufficient Drying

A

PA12 moisture absorption is lower than PA6/PA66 but hydrolysis problems also exist; 0.1% moisture content is the quality red line for its processing.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
