Q1: What is the primary function of Viscofil White A-RCL 30 in polymer systems?
A: Viscofil White A-RCL 30 is a high-performance white pigment masterbatch designed to provide excellent opacity, brightness, and uniform dispersion in thermoplastic polymers—particularly polyolefins such as PP and PE. It functions primarily as a cost-effective whitening and hiding agent while supporting consistent melt processing behavior.
Q2: Is this pigment suitable for food-contact applications?
A: Viscofil White A-RCL 30 is formulated for use in polymers intended for non-food-contact applications. For food-contact compliance, customers must consult Clariant’s regulatory documentation and verify suitability against applicable regional regulations through formal testing and approval processes.
Q3: How does Viscofil White A-RCL 30 differ from standard titanium dioxide masterbatches?
A: Unlike conventional TiO₂ masterbatches, Viscofil White A-RCL 30 incorporates proprietary surface treatment and carrier resin technology optimized for enhanced dispersion stability, reduced plate-out, and improved rheological compatibility—especially in thin-walled or high-shear extrusion processes.
Q4: What is the recommended dosage range for optimal performance?
A: Dosage depends on the base polymer, desired whiteness level, and part geometry—but it is typically used at low concentrations, generally ranging from 0.1% to 2% by weight. Optimization is best achieved through small-scale trials under actual processing conditions.
