Low-Temperature Impact of PCTG Products
Problem Phenomenon
The products become brittle at low temperatures (below -20°C) and are easily broken by impact.
Cause Analysis
Although PCTG has good low-temperature toughness, the movement of molecular chains is restricted in extreme cold and there is still a tendency to embrittle.
Solution
Use toughened grades; avoid notches and sharp corners in product design; reduce internal stress.
Key Takeaway
The low-temperature toughness of PCTG needs to be evaluated for the specific use temperature.
