PLA products soften and deform at high temperature
Problem Phenomenon
PLA products soften and deform when used in environments above 55-65°C.
Cause Analysis
The glass transition temperature of PLA is about 55-60°C and the melting point is 150-170°C; the heat resistance is poor, and it softens above Tg.
Solution
Use heat-resistant PLA grades (crystalline type HDT can be improved); annealing heat treatment to improve heat resistance; mark the use temperature limit.
Key Takeaway
The heat resistance of PLA is one of the biggest limitations of its application.
