PA410 has lower moisture absorption than PA6/PA66
Problem Phenomenon
PA410 has lower moisture absorption than PA6/PA66 and good dimensional stability, but this is not fully utilized in applications
Cause Analysis
（1）The moisture content of PA410 is 0.8-1.5%, lower than PA6, but PA6 parameters are still used in design
（2）The low moisture absorption advantage of PA410 is not reflected in precision products
（3）The moisture conditioning process still follows the PA66 standard and does not match
（4）The drying conditions follow PA66 and are too strict
（5）Customers do not understand the low moisture absorption advantage of PA410
Solution
（1）Use the actual moisture absorption rate of PA410 0.8-1.5% in design
（2）Prefer PA410 in precision dimension products
（3）Develop a special moisture conditioning process for PA410
（4）The drying conditions are executed at 80-100°C/6-8h without excessive drying
（5）Promote the low moisture absorption advantage of PA410
Key Takeaway
The low moisture absorption of PA410 requires dedicated design and moisture conditioning
