Low-temperature performance changes of PA-type materials require evaluation of applicability
Problem Phenomenon
Low-temperature performance changes of PA-type materials require evaluation of applicability
Cause Analysis
Cellulose acetate butyrate impact strength decreases and brittleness increases at low temperature
Dry-state PA low-temperature brittleness is more severe
PA12 has good low-temperature resistance (-40°C) but lower temperatures need verification
PA66 has high low-temperature rigidity but low impact
PA46 low-temperature performance is better than PA66 but still needs evaluation
Solution
Perform low-temperature impact testing before low-temperature use
Conditioning treatment to improve low-temperature toughness
PA12 preferred for low-temperature applications
PA66 requires toughening modification at low temperature
PA46 has good low-temperature rigidity, toughness needs verification
Key Takeaway
PA at low temperature requires impact testing and selection of suitable grades
