Decreased Low-Temperature Impact Strength of PC
Sorun Belirtisi
The impact strength of PC decreases significantly at low temperatures (below -20°C).
Neden Analizi
PC has a tendency to low-temperature embrittlement; although the Tg is about 150°C, the secondary relaxation is in the low-temperature region.
Çözüm
Use a low-temperature toughened PC grade; avoid notches and sharp corners in the design.
Temel Çıkarım
PC low-temperature impact also has limitations.
