Q1: What is the primary application of Hostatint Black GR 30?
A: Hostatint Black GR 30 is a highly concentrated, solvent-free color paste specifically developed for coloring polyolefin compounds—especially polypropylene (PP) and polyethylene (PE)—in applications such as injection molding, blow molding, and extrusion. It is widely used in packaging, automotive interior components, and consumer goods where consistent jet-black shade and excellent dispersion are required.
Q2: Is Hostatint Black GR 30 compatible with food-contact polyolefins?
A: Yes, Hostatint Black GR 30 is formulated to comply with global food-contact regulations for polyolefins, including FDA 21 CFR §178.3297 and EU Framework Regulation (EC) No 1935/2004. Its pigment system and carrier matrix are selected to minimize extractables and support regulatory compliance when used at typical dosage levels in approved polymer matrices.
Q3: How should this color paste be incorporated into polyolefin compounds?
A: Hostatint Black GR 30 is designed for direct addition during compounding—typically via side-stuffer feeder or gravimetric dosing unit—and achieves excellent dispersion without requiring pre-dilution. For optimal results, it is recommended to incorporate the paste upstream of the final mixing zone in twin-screw extruders, allowing sufficient residence time and shear for uniform distribution.
Q4: Does this product offer good thermal stability during processing?
A: Yes, Hostatint Black GR 30 demonstrates robust thermal stability under standard polyolefin processing conditions (up to approximately 260 °C), with minimal risk of charring or hue shift. Its optimized organic black pigment system and thermally stable carrier ensure consistent color performance across repeated processing cycles and high-shear environments.
