Q1: What is the primary application field for Viscofil Blue B2G 30 VP3494?
A: This pigment is specifically developed for high-performance coloration of thermoplastic polymers—especially polyolefins such as PP and PE—in applications requiring excellent heat stability, dispersion consistency, and low volatility during processing.
Q2: How does Viscofil Blue B2G 30 VP3494 differ from conventional blue pigments in polyolefin coloring?
A: It features a proprietary surface treatment optimized for masterbatch production, delivering superior melt dispersibility, reduced filter pressure buildup, and enhanced batch-to-batch color reproducibility—particularly under high-shear compounding conditions.
Q3: Is this pigment suitable for food-contact or medical-grade polymer applications?
A: Viscofil Blue B2G 30 VP3494 is formulated without heavy metals and complies with general regulatory expectations for indirect food contact in polyolefins, subject to final formulation review and end-use compliance verification by the compounder or converter.
Q4: What is the recommended dosage range in polyolefin masterbatches?
A: Typical usage levels range from 0.1% to 2% by weight in final compounds, depending on the desired shade strength and substrate opacity—dosage should be optimized via small-scale trials to balance color performance and process efficiency.
