Decreased Transparency and Haze of PCTG Injection Molded Products
문제 현상
The transparency of PCTG products decreases, showing a hazy or translucent appearance.
원인 분석
Insufficient drying, the moisture does not meet the standard (>0.03%), hydrolysis and bubbles are generated during processing, the processing temperature is too high causing degradation, and the mold roughness is poor.
해결 방법
Dry at 65-70°C for 4-6h until the moisture is <0.03% with a dew point ≤-40°C; control the processing temperature at 220-250°C; mirror-polish the mold.
핵심 요약
The basis of PCTG transparency lies in sufficient drying and temperature control.
