Holliday Ultramarine Blue FRX – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Holliday Ultramarine Blue FRX in polymer systems?

A: Holliday Ultramarine Blue FRX is a heat-stable, non-bleeding ultramarine blue pigment specifically engineered for use in thermoplastic and thermoset polymers. Its main function is to provide consistent, vibrant blue coloration while maintaining excellent dispersion and thermal stability during high-temperature processing such as injection molding or extrusion.

Q2: Is Holliday Ultramarine Blue FRX suitable for food-contact applications?

A: Holliday Ultramarine Blue FRX is formulated for general industrial and decorative polymer applications. It is not certified for direct food-contact use under current global regulatory frameworks. Customers requiring food-safe colorants should consult with Holliday Technical Services to explore alternative compliant solutions.

Q3: How does Holliday Ultramarine Blue FRX perform in acidic environments?

A: Like most ultramarine pigments, Holliday Ultramarine Blue FRX is sensitive to strong acids and may undergo color degradation or fading when exposed to low-pH conditions. It is recommended for use in neutral to mildly alkaline polymer matrices and should be avoided in formulations containing acidic additives or in applications with prolonged acid exposure.

Q4: What is the typical dosage range for Holliday Ultramarine Blue FRX in polyolefin compounds?

A: Dosage depends on the desired shade intensity and base resin characteristics, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in polyolefin systems. Optimal loading should be determined through lab-scale trials to balance color strength, dispersion quality, and processability.

Q5: Can Holliday Ultramarine Blue FRX be used alongside other organic pigments or effect pigments?

A: Yes—Holliday Ultramarine Blue FRX demonstrates good compatibility with many common organic pigments and effect pigments (e.g., titanium dioxide, mica-based pearlescents) in multi-pigment blends. However, due to potential reactivity with certain sulfide- or heavy metal–based pigments, compatibility testing in the final formulation is strongly recommended prior to full-scale production.
