Low-Temperature Impact of PCTG Products
문제 현상
The products become brittle at low temperatures (below -20°C) and are easily broken by impact.
원인 분석

해결 방법
Use toughened grades; avoid notches and sharp corners in product design; reduce internal stress.
핵심 요약
The low-temperature toughness of PCTG needs to be evaluated for the specific use temperature.
