Q1: What types of polymer systems is ERICW BC31021 Color Paste compatible with?
A: ERICW BC31021 is formulated for compatibility with common thermoplastics including polyethylene (PE), polypropylene (PP), and polystyrene (PS), as well as certain engineering resins. Compatibility should be verified under actual processing conditions due to variations in resin grade, additives, and thermal history.
Q2: How should ERICW BC31021 be incorporated into a polymer melt?
A: It is typically introduced via gravimetric or volumetric dosing directly into the extruder feed throat or side feeder. Pre-blending with carrier resin or masterbatch dilution may be used to ensure uniform dispersion, especially at lower dosage levels.
Q3: Is ERICW BC31021 suitable for food-contact applications?
A: ERICW BC31021 is designed for general industrial use. For food-contact applications, end-use compliance must be confirmed by the compounder or converter through full regulatory assessment—including migration testing and verification against applicable regional requirements—based on the final formulation and processing conditions.
Q4: What storage conditions are recommended to maintain stability?
A: Store in original sealed containers at temperatures between 5°C and 30°C, away from direct sunlight and sources of heat or moisture. Avoid freezing, and ensure containers remain tightly closed when not in use to prevent skinning or viscosity changes.
