Q1: What is the primary function of Imerys CelTix Pigment in polymer systems?
A: Imerys CelTix Pigment is a functional mineral-based pigment designed to provide controlled opacity, enhanced surface texture, and improved dimensional stability in thermoplastics and thermosets—without significantly compromising mechanical performance or processability.
Q2: Is CelTix Pigment suitable for food-contact or medical-grade applications?
A: CelTix Pigment is manufactured under strict quality control and is compatible with many regulatory-compliant formulations. However, final regulatory approval depends on the complete formulation, processing conditions, and end-use requirements—users must conduct appropriate testing and consult relevant regulatory guidelines for their specific application.
Q3: How does CelTix Pigment differ from conventional calcium carbonate or titanium dioxide pigments?
A: Unlike standard fillers or opacifiers, CelTix Pigment features a tailored particle morphology and surface treatment that promotes uniform dispersion, reduces agglomeration, and delivers more consistent optical and rheological behavior—particularly in demanding extrusion and injection molding processes.
Q4: What processing methods are recommended for optimal dispersion of CelTix Pigment?
A: CelTix Pigment is engineered for compatibility with standard compounding equipment. Best results are achieved using high-shear twin-screw extrusion or intensive internal mixers, with attention to temperature profile and residence time to ensure full deagglomeration without thermal degradation of the host polymer.
Q5: Can CelTix Pigment be used in combination with other additives such as UV stabilizers or flame retardants?
A: Yes—CelTix Pigment exhibits good compatibility with common polymer additives. However, interactions should be evaluated empirically in the final formulation, as synergistic or antagonistic effects may influence performance, especially in multi-additive systems requiring precise balance.
