Q1: What types of polymer systems is Meichen Green GH2 Color Paste compatible with?
A: Meichen Green GH2 Color Paste is formulated for compatibility with common thermoplastic resins including polyethylene (PE), polypropylene (PP), and polystyrene (PS). It demonstrates good dispersion stability in both melt-processing and masterbatch applications, though compatibility testing under actual processing conditions is recommended prior to full-scale use.
Q2: How should Meichen Green GH2 be incorporated into a polymer formulation?
A: The paste is typically introduced during compounding or extrusion using standard high-shear mixing equipment. For optimal dispersion, pre-drying the base polymer is advised, and residence time/temperature profiles should align with the thermal stability window of the pigment system. It is generally used at low concentrations and may require adjustment based on target shade depth and substrate opacity.
Q3: Does Meichen Green GH2 meet regulatory requirements for food-contact or toy applications?
A: Meichen Green GH2 is designed to comply with general industry expectations for colorants in non-food-contact industrial plastics. It is not certified for direct food-contact or regulated toy applications unless explicitly validated by the end-user against applicable regional requirements. Customers requiring compliance for sensitive applications must conduct their own regulatory assessment and obtain appropriate documentation from their supply chain.
Q4: What are the storage and handling recommendations for this color paste?
A: Store in original sealed containers at temperatures between 5°C and 30°C, away from direct sunlight and sources of heat or moisture. Avoid freezing. Stir gently before use to ensure homogeneity, and maintain clean handling practices to prevent contamination. Shelf life is typically 12 months when stored under recommended conditions.
