How to identify the quality of PET masterbatch? Let us first understand the main technical indicators of PET masterbatch:
1. Resistance to migration (level) [≥4]
2. Moisture content (%) [≤0.30]8, total color difference [≤1.50]
3. Melting temperature (oC) [125 ~ 200]
4, PET masterbatch Dispersibility: [colorless dots, stripes]
5, light fastness (grade) [5-8]
6, polyester masterbatch looks grainy, uniform particles, consistent color
7, heat resistance (grade) [≥ 4]
