Q1: What types of polymers is this color paste compatible with?
A: Clariant Hostatint Black A-NY 100-ST VP 516... Color Paste is formulated for compatibility with a broad range of thermoplastics, including polyolefins (PP, PE), styrenics (PS, ABS), and engineering resins such as PA and PC. Compatibility should always be verified under actual processing conditions.
Q2: How should this color paste be incorporated into polymer melts?
A: It is typically introduced via gravimetric or volumetric dosing directly into the extruder feed throat or injection molding hopper. Pre-blending with base resin prior to melting is also acceptable and may improve dispersion uniformity, especially in high-viscosity systems.
Q3: Does this product contain heavy metals or restricted substances?
A: This color paste is manufactured without intentionally added heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) and complies with Clariant’s internal Restricted Substances List (RSL). Regulatory compliance for specific end-use applications remains the responsibility of the formulator.
Q4: What is the typical dosage range for achieving full black opacity?
A: Full black opacity is generally achieved at concentrations between 0.1% and 2% by weight, depending on polymer type, melt viscosity, processing temperature, and required depth of shade. Lower dosages often suffice in thin-walled parts or high-clarity matrices.
Q5: Is this color paste suitable for food-contact or medical-grade applications?
A: This product is not pre-qualified for food-contact or medical applications. Customers intending such use must conduct full regulatory evaluation—including migration testing and biocompatibility assessment—according to applicable regional requirements and final part specifications.
