Increased brittleness of PA12 in extremely low temperature environments (below -40°C)
Problem Phenomenon
The brittleness of PA12 increases in extremely low temperature environments (below -40°C), affecting low-temperature applications
Cause Analysis
（1）The long carbon chain structure of PA12 restricts molecular chain movement at extremely low temperatures
（2）Although PA12 is resistant to low temperature (-40°C), its performance declines at lower temperatures
（3）The flexibility advantage of PA12 weakens in low-temperature environments
（4）Adding plasticizers improves low-temperature performance but affects other properties
（5）Comparison of low-temperature resistance grades of PA12 and PA11
Solution
（1）Select low-temperature-resistant PA12 modified varieties
（2）Use PA12 with low-temperature toughening agents for use below -40°C
（3）Evaluate the actual low-temperature requirements and select suitable materials
（4）Compare the low-temperature performance with PA11
（5）Optimize the formulation to improve low-temperature toughness
Key Takeaway
PA12 low-temperature applications need to evaluate actual requirements
