Transparency of polyamide 46 (high-temperature nylon) Significantly Decreased After Modification
Problem Phenomenon
The transparency of polyamide 46 (high-temperature nylon) significantly decreases after modification, the haze increases, and it does not meet the requirements of transparent products
Cause Analysis
The refractive index of the added additive does not match that of polyamide 46 (high-temperature nylon)
The additive is unevenly dispersed, producing scattering
The processing temperature is too high, and the additive degrades and discolors
The amount added is too large, affecting the transparency
The change in crystallinity affects the transparency
Solution
Select an additive with a matching refractive index
Ensure the additive is evenly dispersed
Control the processing temperature to avoid additive degradation
Reduce the amount added
Control the crystallization conditions
Key Takeaway
The decrease in transparency needs to be addressed from refractive index matching and dispersion
