Low Heat Deflection Temperature of PCTG Products
Problem Phenomenon
The products deform during high-temperature use.
Cause Analysis
The heat deflection temperature of PCTG is usually 65-75°C, which is relatively low, and it softens at high temperatures.
Solution
For high-temperature applications, consider copolyester modified grades or PCTA; mark the use temperature ≤65°C.
Key Takeaway
The heat deflection temperature of PCTG is a limiting factor for its application.
