Q1: What is the primary application field for Hostafine Black SP-T 30?
A: Hostafine Black SP-T 30 is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers, where high jetness, excellent dispersion stability, and low plate-out are required.
Q2: Is this paste compatible with standard polypropylene (PP) and polyethylene (PE) processing conditions?
A: Yes — Hostafine Black SP-T 30 is formulated for robust performance under typical PP and PE extrusion and injection molding temperatures, offering good thermal stability and minimal pigment degradation during melt processing.
Q3: How should the paste be incorporated into a polymer matrix?
A: It is typically added directly to the base polymer via gravimetric or volumetric dosing systems prior to extrusion. Pre-blending with carrier resin or masterbatch dilution is not required, though dosage depends on formulation requirements and desired shade intensity.
Q4: Does this product contain heavy metals or halogenated compounds?
A: Hostafine Black SP-T 30 is manufactured without intentionally added heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) or halogenated solvents, in alignment with Clariant’s commitment to sustainable and regulatory-compliant color solutions.
Q5: What is the recommended storage condition to maintain paste stability?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and sources of heat. Avoid freezing, as it may affect rheology and dispersion integrity.
