We all know the role of polyester masterbatch and its broad, then the quality is how to identify it?

How to identify the quality of polyester masterbatch quality?

     May wish to first look at the main technical indicators of polyester masterbatch:

     1, resistance to migration (grade) [≥4]

     2, moisture content (%) [≤ 0.30] 8, the total color difference [≤ 1.50]

     3, melting temperature (oC) [125 ~ 200]

     4, polyester masterbatch dispersibility: [colorless point, stripes]

     5, light fastness (grade) [5-8]

     6, polyester masterbatch appearance of granular, uniform particles, consistent color

     7, heat resistance (grade) [≥4]
