PC/ABS heat deflection temperature insufficient
Problem Phenomenon
PC/ABS HDT does not meet heat resistance requirements (e.g., automotive interior 80-110°C).
Cause Analysis
PC/ABS HDT depends on PC content and processing conditions; HDT is about 100-120°C.
Solution
Increase PC content; full annealing (80-100°C/2h) to increase HDT.
Key Takeaway
PC/ABS heat resistance can be improved through formulation and annealing.
