Change in chemical resistance of polyamide 12 (long carbon chain nylon) after modification
Problem Phenomenon
The chemical resistance of polyamide 12 (long carbon chain nylon) changes after modification, and the resistance to specific chemicals decreases or increases
Cause Analysis
（1）The added additives change the chemical structure of the material
（2）The toughening agent reduces the chemical resistance
（3）The flame retardant may increase the chemical resistance
（4）The interaction of the components in the formulation is complex
（5）The matrix characteristics of polyamide 12 (long carbon chain nylon) change
Solution
（1）Evaluate the change in chemical resistance after modification
（2）Select a toughening agent that does not affect the chemical resistance
（3）Utilize the chemical resistance improvement of the flame retardant
（4）Comprehensively consider the influence of each component of the formulation
（5）Maintain the matrix characteristics
Key Takeaway
Chemical resistance needs to evaluate the overall influence of the modified formulation
