ASA heat deflection 101°C
Problem Phenomenon
ASA heat deflection temperature 101°C annealed, heat resistance management.
Cause Analysis
ASA heat deflection temperature 101°C (annealed 0.45MPa); Vicat softening 97°C; heat resistance performance; application temperature; long-term stability; grade differences.
Solution
①Heat deflection 101°C reference; ②application temperature evaluation; ③long-term stability; ④grade selection; ⑤heat resistance verification.; After adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA heat deflection temperature is a heat resistance indicator; application evaluation ensures safety; verification ensures long-term.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
