ABAK heat resistance balance
Sorun Belirtisi
The heat deflection temperature of ABAK is between that of ABS and PA; the ratio affects heat resistance performance, and the application temperature should be evaluated.
Neden Analizi
The heat deflection temperature of ABS is 85~100℃, and that of PA6 is 180~220℃; the alloy HDT is about 110~150℃ depending on the ratio; a high PA ratio gives good heat resistance but is difficult to process; a high ABS ratio gives good processability but reduced heat resistance.
Çözüm
①Select the ratio according to application temperature requirements; ②glass fiber reinforcement raises HDT to 160℃+; ③verify heat deflection temperature with actual measurements; ④evaluate long-term heat resistance.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
ABAK heat resistance is a function of the ratio; glass fiber reinforcement is the improvement means; actual measurement verification is more reliable than theoretical estimation.; After confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
