Q1: What is the primary function of ZAP-C Pigment in polymer systems?
A: ZAP-C Pigment is a specialized heat-stable, non-migrating colorant designed to provide consistent chromatic performance and excellent dispersion in high-temperature thermoplastic processing, particularly in polyolefins and engineering resins.
Q2: Is ZAP-C suitable for food-contact applications?
A: ZAP-C is formulated without heavy metals or restricted aromatic amines commonly associated with azo-based pigments. While it is not pre-certified for all food-contact regulations, its composition supports compliance pathways where regulatory evaluation and end-product testing are conducted by the compounder or converter.
Q3: How does ZAP-C compare to conventional organic pigments in terms of thermal stability?
A: ZAP-C exhibits significantly enhanced thermal stability compared to standard organic pigments, maintaining color integrity during extended residence times at temperatures up to 300°C—making it well-suited for demanding extrusion and injection molding processes.
Q4: What is the recommended dosage range for optimal performance?
A: Dosage depends on the base polymer, desired shade intensity, and processing conditions; however, ZAP-C is typically used at low concentrations, generally ranging from 0.1% to 2% by weight, with most applications falling within the lower half of this range.
