Q1: What types of polymer systems is ERICW BC11040 Color Paste compatible with?
A: ERICW BC11040 is formulated for compatibility with a broad range of thermoplastics, including polyolefins (PP, PE), ABS, PS, and certain engineering resins. Compatibility should be verified through preliminary dispersion and thermal stability testing under actual processing conditions.
Q2: How should ERICW BC11040 be incorporated into the base resin?
A: It is typically introduced via masterbatch dilution or direct high-shear mixing during compounding. Pre-drying is not required, but uniform dispersion is critical—optimal results are achieved using twin-screw extruders with adequate residence time and temperature control.
Q3: Does ERICW BC11040 contain heavy metals or restricted substances?
A: ERICW BC11040 is manufactured without intentionally added lead, cadmium, mercury, or hexavalent chromium, and complies with widely recognized industry expectations for general-purpose colorants. Specific regulatory compliance depends on final application and regional requirements, and full declaration of components is available upon request.
Q4: What is the recommended dosage range for achieving target color strength?
A: Dosage depends on the base polymer, desired chroma, and processing method, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight. Optimal loading should be determined experimentally to balance color development, dispersion quality, and mechanical performance.
Q5: How stable is the colorant under standard injection molding or extrusion conditions?
A: ERICW BC11040 demonstrates good thermal stability up to typical processing temperatures for common thermoplastics. However, prolonged exposure above 260 °C or extended residence time may affect hue consistency—validation under end-use processing parameters is strongly advised.
