ABAK impact strength improvement
Sorun Belirtisi
ABAK utilizes ABS to improve the low-temperature and dry-state impact strength of PA, but an improper ratio actually reduces it.
Neden Analizi
PA has low dry-state and low-temperature impact strength; the ABS butadiene rubber phase provides toughness; however, as ABS dosage increases, yield strength and impact strength actually decrease while elongation at break increases; the improvement is limited when the compatibilizer is insufficient.
Çözüm
①Optimize the ABS ratio (usually 30~50%); ②add sufficient compatibilizer; ③balance strength and toughness according to the application; ④verify with low-temperature impact tests.
Temel Çıkarım
ABAK impact strength improvement depends on ratio and compatibilizer optimization; more ABS is not always better; testing verifies the actual improvement effect.; After confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
