Q1: What types of polymer systems is ERICW BC41021 Color Paste compatible with?
A: ERICW BC41021 is formulated for use in thermoplastic polymers 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 resins requiring extended thermal exposure above 280°C.
Q2: How should ERICW BC41021 be incorporated into a compound or masterbatch?
A: It is typically added directly to the base polymer during extrusion or compounding using standard twin-screw equipment. Pre-blending with a portion of the carrier resin prior to feeding may improve dispersion uniformity. Avoid excessive shear or prolonged residence time at elevated temperatures to maintain color integrity.
Q3: Is ERICW BC41021 suitable for applications requiring food contact compliance?
A: ERICW BC41021 is designed for industrial and general-purpose coloring applications. It is not pre-certified for food-contact use; customers must conduct their own regulatory evaluation based on final formulation, processing conditions, and applicable regional requirements.
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 it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to the total formulation.
