Q1: What types of polymer systems is this color paste compatible with?
A: Clariant Colanyl Oxide Black B 510 VP 6089 is formulated for use in a broad range of thermoplastics, including polyolefins (PP, PE), styrenics (PS, ABS), and engineering plastics such as PA and PC. Compatibility should always be verified under actual processing conditions due to formulation-specific interactions.
Q2: How is the dispersion quality of this black oxide paste typically evaluated?
A: Dispersion quality is assessed visually and instrumentally after melt compounding — commonly via gloss measurement, filter pressure buildup (FPB) tests, or microscopic examination of thin films. The paste is designed to deliver fine, stable pigment distribution with low agglomerate content in standard extrusion processes.
Q3: Does this product contain any heavy metals or restricted substances?
A: This color paste is manufactured without intentionally added lead, cadmium, mercury, or hexavalent chromium, in alignment with global regulatory expectations for polymer colorants. It is not certified for food-contact applications unless specifically validated by the end-user under applicable local requirements.
Q4: What is the recommended dosage range for achieving full black opacity?
A: Full black opacity is generally achieved at dosages ranging from 0.1% to 2% by weight, depending on base polymer, layer thickness, and desired jetness or undertone. Optimization is advised through small-scale trials to balance performance, cost, and processing stability.
