In order to control strictly the quality of masterbatch,we import advanced technology and equipment (Injection-moulding Machine,Blown-film Machine,Extrusion Machine) to make sure the quality of the final products made from our masterbatch.
Moisture: ≤0.2%
Tinting Strength: it should be between -5% to +5% compared with the standard sample.
Color Shade: basically the same compared with the standard sample.
Chromatism: ≤ 3, compared with the standard sample.
Migration Resistance: ≥ 4.
Heat Resistance: ≥ 6
Dispersibility : ≥ Excellent
Appearance: the masterbatch should be even pallets with glossy surface and identical color. and the percentage points for two pellets adhering together should not surpass 0.2%.
