Q1: What types of polymer systems is Hostafine Trans Oxide Yellow R 30 compatible with?
A: This transparent oxide yellow color paste is specifically formulated for use in thermoplastic polymers including polyolefins (PP, PE), polystyrene (PS), ABS, and certain engineering plastics. It is not recommended for high-temperature engineering resins requiring prolonged exposure above 280 °C or for PVC applications due to thermal stability limitations.
Q2: How does the transparency of this yellow compare to organic yellow pigments?
A: As an iron-based transparent oxide pigment system, Hostafine Trans Oxide Yellow R 30 offers superior lightfastness and thermal stability compared to many organic yellows, while maintaining good transparency in thin sections and clear matrices — though its chroma and hue intensity are generally more subdued than high-performance organic alternatives.
Q3: What is the typical dosage range for achieving target shade strength?
A: Dosage depends on the base polymer, required opacity/transparency balance, and desired shade intensity. In most polyolefin applications, effective coloring is typically achieved at concentrations ranging from 0.1% to 2% by weight — with lower levels often sufficient for light tints and higher loadings used when masking substrate color or enhancing depth in thicker parts.
Q4: Is this product suitable for food-contact or medical-grade applications?
A: Hostafine Trans Oxide Yellow R 30 is not pre-qualified for direct food-contact or regulated medical device applications. Its suitability for such uses requires full formulation evaluation, including regulatory review of all components, migration testing under intended conditions, and compliance verification against applicable regional requirements.
