Q1: What types of polymer systems is Meichen Blue BH2 Color Paste compatible with?
A: Meichen Blue BH2 Color Paste is formulated for compatibility with a broad range of thermoplastics and thermosets, including polyolefins (PP, PE), PVC, PS, ABS, and engineering resins such as PA and PC. Compatibility testing under actual processing conditions is recommended prior to full-scale production.
Q2: How should Meichen Blue BH2 Color Paste be dispersed in the base resin?
A: Optimal dispersion is achieved using standard compounding equipment such as twin-screw extruders or high-shear mixers. Pre-blending with a portion of the base polymer before extrusion helps ensure uniform distribution. Avoid excessive thermal history to preserve color strength and stability.
Q3: Is Meichen Blue BH2 Color Paste suitable for applications requiring heat stability during processing?
A: Yes — Meichen Blue BH2 Color Paste exhibits good thermal stability up to typical polymer processing temperatures (e.g., 180–240 °C depending on residence time and matrix). Its performance remains consistent under standard injection molding, extrusion, and blow molding conditions.
Q4: What is the typical dosage range for achieving target shade intensity?
A: Dosage depends on the base polymer, desired chroma, and processing method, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to the total formulation. Pilot trials are advised to determine the optimal loading for each application.
Q5: Does Meichen Blue BH2 Color Paste contain heavy metals or restricted substances?
A: Meichen Blue BH2 Color Paste is manufactured without intentionally added lead, cadmium, mercury, hexavalent chromium, or other heavy metals commonly restricted under global regulatory frameworks. It is designed to support compliance with major industry expectations for general-purpose colorants, though final regulatory validation remains the responsibility of the compounder or end-user.
