Significant transparency decline of polyamide 12 (long carbon chain nylon) after modification
Fenómeno del problema
The transparency of polyamide 12 (long carbon chain nylon) decreases significantly after modification, the haze increases, and it does not meet the requirements of transparent products
Análisis de la causa
（1）The refractive index of the added additives does not match that of polyamide 12 (long carbon chain nylon)
（2）The additive dispersion is uneven, producing scattering
（3）The processing temperature is too high and the additives degrade and discolor
（4）The addition amount is too large, affecting the transparency
（5）Changes in crystallinity affect the transparency
Solución
（1）Select additives with matching refractive index
（2）Ensure uniform dispersion of the additives
（3）Control the processing temperature to avoid additive degradation
（4）Reduce the addition amount
（5）Control the crystallization conditions
Conclusión clave
The transparency decline needs to be addressed from refractive index matching and dispersion
