PI imidization shrinkage too large
Fenómeno del problema
The dimensional shrinkage of the product after imidization exceeds expectations
Análisis de la causa
Volume shrinkage caused by the chemical structure transformation of imidization (10-15%); solvent volatilization
Solución
Consider the imidization shrinkage allowance in design; control the initial PAA dimensions of the product
Conclusión clave
The chemical shrinkage of PI is a factor that must be considered in design and processing
