Q1: What is the primary application field for Renol Orange RL-HW 30?
A: Renol Orange RL-HW 30 is specifically developed for high-temperature polymer processing applications, particularly in polyolefins such as PP and HDPE, where thermal stability and color consistency during extrusion or injection molding are critical.
Q2: Is this pigment suitable for food-contact plastics?
A: Renol Orange RL-HW 30 is designed for use in polymers intended for food-contact applications, subject to compliance with applicable regional regulations. Users must verify suitability based on their specific formulation, processing conditions, and end-use requirements through appropriate regulatory assessment.
Q3: How does RL-HW 30 differ from standard Renol Orange RL-HW grades?
A: The “30” designation indicates a pre-dispersed, carrier-based masterbatch formulation optimized for enhanced dispersion efficiency and reduced dust generation. It offers improved handling and more consistent dosing compared to dry pigment forms, especially in automated compounding systems.
Q4: What is the recommended dosage range for optimal coloration?
A: Dosage depends on the desired shade intensity, polymer type, and processing method, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight of the final compound—to achieve vibrant, uniform orange hues without compromising physical properties.
