Q1: What types of polymer systems is ERICW BC31005 Color Paste compatible with?
A: ERICW BC31005 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 testing under actual processing conditions is recommended to confirm dispersion stability and color consistency.
Q2: How should ERICW BC31005 be incorporated into a polymer compound?
A: It is typically introduced during compounding via twin-screw extrusion or high-speed mixer blending. Pre-drying is not required, but good mechanical shear and adequate residence time are essential for optimal pigment dispersion and color development.
Q3: Is ERICW BC31005 suitable for applications requiring heat stability during processing?
A: Yes — BC31005 is engineered for thermal stability up to typical polymer processing temperatures (e.g., 200–260 °C), supporting stable color performance in extrusion, injection molding, and blow molding without significant degradation or hue shift.
Q4: What is the typical dosage range for achieving target color intensity?
A: Dosage depends on the base polymer, desired shade depth, and opacity requirements, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight — with higher loadings reserved for deep tones or opaque effects.
Q5: Does ERICW BC31005 contain heavy metals or restricted substances?
A: ERICW BC31005 is manufactured without intentionally added lead, cadmium, mercury, or hexavalent chromium, and conforms to widely accepted industry expectations for responsible pigment formulation. For regulated end-use applications, consult your ERICW technical representative for compliance documentation aligned with your regional and sector-specific requirements.
