Q1: What types of polymer systems is Meichen RH1 Color Paste compatible with?
A: Meichen RH1 Color Paste is formulated for compatibility with a broad range of thermoplastics and thermosets, including polyolefins (PP, PE), PVC, ABS, PS, and engineering resins such as PA and PC. Compatibility should be verified under actual processing conditions due to formulation-specific interactions.
Q2: How should Meichen RH1 Color Paste be incorporated into the base resin?
A: It is typically introduced via gravimetric or volumetric dosing directly into the extruder feed throat or injection molding hopper. Pre-blending with a portion of the base resin may improve dispersion uniformity, especially in high-viscosity or low-shear systems.
Q3: Does Meichen RH1 Color Paste contain heavy metals or restricted substances?
A: Meichen RH1 Color Paste is manufactured without intentionally added lead, cadmium, mercury, or hexavalent chromium, and complies with widely recognized industry expectations for general-purpose colorants. For regulated applications (e.g., food contact, toys), formal compliance documentation must be requested and validated per end-use requirements.
Q4: What is the typical dosage range for achieving target color intensity?
A: Dosage depends on the desired shade depth, base resin transparency, and processing method, but generally ranges from 0.1% to 2% by weight. Lower concentrations are often sufficient for deep shades, while pastel or translucent effects may require careful optimization.
