Q1: What is the primary chemical composition of Holliday 60 Ultramarine Pigment?
A: Holliday 60 is a synthetic sodium aluminosilicate pigment with sulfur-based chromophores, delivering its characteristic intense blue hue through a crystalline sodalite-type structure. It contains no heavy metals such as lead, cadmium, or chromium.
Q2: Is Holliday 60 suitable for use in polyolefin compounds like PP and HDPE?
A: Yes — Holliday 60 exhibits excellent thermal stability and dispersion behavior in polyolefins during standard melt processing. It is widely used in injection molding, blow molding, and extrusion applications where consistent color development and minimal plate-out are required.
Q3: How does Holliday 60 perform under acidic conditions?
A: Like most ultramarine pigments, Holliday 60 is sensitive to low-pH environments and may undergo chromophore degradation when exposed to strong acids. It is not recommended for applications involving prolonged contact with acidic media or formulations below pH 5.
Q4: Can Holliday 60 be used in food-contact plastics?
A: Holliday 60 is manufactured to meet general purity requirements for pigments used in non-intent food-contact applications, but final regulatory compliance depends on the full formulation, processing conditions, and target jurisdiction. Users must conduct appropriate migration testing and verify suitability against applicable local regulations.
Q5: What is the typical dosage range for achieving full opacity in plastic masterbatches?
A: Dosage depends on the base polymer, desired shade intensity, and processing method, but Holliday 60 is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight in masterbatch formulations.
