Extremely Fast Crystallization Speed of PA46
Sorun Belirtisi
The crystallization speed of PA46 is extremely fast; improper mold temperature causes abnormal crystallinity and large performance fluctuations
Neden Analizi
The crystallization speed of PA46 is several times faster than that of PA66, and crystallization is incomplete at low mold temperatures
Only a high mold temperature (100-140°C) can obtain high crystallinity and high performance
Mold temperature fluctuations cause crystallinity fluctuations and unstable performance
The crystallinity difference between the inside and outside of thick-walled products is large
Rapid crystallization leads to high rigidity and low toughness of the product
Çözüm
Use a high-temperature mold at 100-140°C to ensure complete crystallization
Stabilize the mold temperature to avoid fluctuations
Thick-walled products need extended cooling to ensure crystallization is complete
Adjust the mold temperature according to performance requirements
Add crystallization nucleating agents to control crystallization
Temel Çıkarım
PA46 crystallization requires a high-temperature mold and stable control
