Q1: What types of polymer systems is ERICW BC51005 Color Paste compatible with?
A: ERICW BC51005 is formulated for broad compatibility with thermoplastic resins including polyolefins (PP, PE), ABS, PS, and certain engineering plastics. It demonstrates good dispersion stability during melt processing and is not recommended for high-temperature engineering polymers requiring extended thermal exposure above 280°C.
Q2: How should ERICW BC51005 be incorporated into a compound or masterbatch?
A: The paste is typically added directly to the base polymer during extrusion or internal mixing. For optimal dispersion, it is recommended to introduce ERICW BC51005 after the polymer has softened but before full melt homogenization. Pre-blending with a small portion of carrier resin may improve distribution in high-viscosity systems.
Q3: Is ERICW BC51005 suitable for applications requiring regulatory compliance for food contact or toys?
A: ERICW BC51005 is designed with non-heavy-metal pigments and low-volatility carriers, supporting compliance pathways for general-purpose applications. However, final regulatory approval depends on the complete formulation, processing conditions, and target market requirements — users must conduct appropriate testing and verification per applicable local regulations.
Q4: What is the typical dosage range for achieving target color intensity?
A: Dosage depends on the base polymer, desired shade depth, and processing method, but ERICW BC51005 is generally used at low concentrations — typically ranging from 0.1% to 2% by weight — to achieve strong chromatic performance without compromising mechanical properties.
