Improvement of PLA modified heat distortion temperature
Problem Phenomenon
The heat distortion temperature of PLA is low and needs to be raised to above 80-100°C.
Cause Analysis
PLA crystallization is insufficient or the matrix itself HDT (amorphous) is only 55-65°C.
Solution
Promote crystallization (nucleating agent + heat treatment) or alloy with high heat-resistant bioplastics.
Key Takeaway
PLA heat-resistant modification is the prerequisite for its high-end applications.
