Q1: What is the primary application of Hostajet Black O-PT Color Paste?
A: Hostajet Black O-PT is specifically formulated for coloring polyolefin-based packaging films and containers, particularly where high jetness, excellent dispersion, and thermal stability during extrusion or injection molding are required.
Q2: Is this paste compatible with food-contact polyolefin applications?
A: Yes — Hostajet Black O-PT is designed for use in food-contact compliant polyolefin systems, subject to final formulation validation and adherence to applicable regional regulatory requirements for indirect food contact.
Q3: How should the paste be incorporated into polyolefin resins?
A: It is typically added directly to the base polymer via gravimetric or volumetric dosing systems prior to extrusion or injection molding. Good mixing efficiency ensures uniform dispersion without agglomeration.
Q4: What is the typical dosage range for achieving target black intensity?
A: Dosage depends on the desired shade depth and substrate thickness, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to the base polymer.
