Q1: What is the primary application field for Renol Yellow HR-HW 30?
A: Renol Yellow HR-HW 30 is specifically developed for high-performance coloration of polyolefins—especially injection-molded and extruded parts requiring excellent thermal stability, low volatility, and good dispersion behavior.
Q2: Is this pigment suitable for food-contact applications?
A: Renol Yellow HR-HW 30 is designed to meet relevant global regulatory expectations for indirect food contact in polyolefin packaging and containers, subject to final formulation validation and compliance with applicable local requirements.
Q3: How does HR-HW 30 perform under high-temperature processing conditions?
A: This pigment demonstrates robust thermal stability during typical polyolefin processing—such as injection molding and extrusion—at temperatures up to 280 °C, with minimal color shift or degradation when properly dispersed.
Q4: What is the recommended dosage range for optimal performance?
A: Dosage depends on the desired shade strength and substrate characteristics, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in polyolefin matrices—to achieve strong yellow hues with good opacity and consistency.
Q5: Does HR-HW 30 require special handling or pre-treatment before compounding?
A: No pre-treatment is required. The pigment is supplied in a free-flowing, dust-reduced form optimized for direct feeding into standard compounding equipment; however, good dispersion practices—including appropriate screw design and melt temperature control—are recommended for best results.
