Q1: What types of polymer systems is Meichen BH2 Color Paste compatible with?
A: Meichen BH2 Color Paste is formulated for compatibility with a broad range of thermoplastics and thermosets, including polyolefins (PP, PE), PVC, PS, ABS, and certain engineering plastics. Performance may vary depending on resin polarity, processing temperature, and shear conditions—compatibility testing under actual production parameters is recommended.
Q2: How should Meichen BH2 Color Paste be incorporated into the base polymer?
A: The paste is typically introduced via high-shear mixing equipment such as twin-screw extruders or high-speed dispersers. Pre-blending with a portion of the base resin prior to main compounding improves dispersion uniformity. Avoid prolonged thermal exposure at elevated temperatures prior to final melt processing.
Q3: Is Meichen BH2 Color Paste suitable for food-contact or medical-grade applications?
A: Meichen BH2 Color Paste is not pre-certified for food-contact or medical use. Its suitability for regulated applications depends on full formulation assessment, including carrier system compliance and final product testing. Customers must verify regulatory alignment with their target market requirements and intended end-use conditions.
Q4: What is the typical dosage range for achieving target color intensity?
A: Dosage depends on desired shade depth, substrate opacity, and processing method, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the base polymer. Stronger tints often require lower loadings, while pastel or translucent effects may need careful optimization.
Q5: Does Meichen BH2 Color Paste contain heavy metals or restricted aromatic amines?
A: Meichen BH2 Color Paste is manufactured without intentionally added heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) or known carcinogenic aromatic amines. It is produced in accordance with current industry best practices for restricted substance management, though full compliance verification requires batch-specific analytical data upon request.
