Q1: What is the primary application area for Hostafine Red F5RK 30?
A: Hostafine Red F5RK 30 is a high-performance organic pigment dispersion designed primarily for coloring polyolefin plastics—especially PP and PE—in applications requiring good thermal stability, low plate-out, and consistent batch-to-batch color reproducibility.
Q2: Is this color paste suitable for food-contact plastic applications?
A: Hostafine Red F5RK 30 is formulated to meet general requirements for food-contact compliance in polyolefins where permitted by applicable regional regulations; however, final regulatory approval depends on the full formulation, processing conditions, and end-use specifications—users must verify compliance with local authorities and conduct required testing.
Q3: How should Hostafine Red F5RK 30 be incorporated into polymer melts?
A: It is typically introduced via gravimetric or volumetric dosing directly into the extruder feed throat or side feeder; pre-mixing with carrier resin is optional but not required due to its optimized rheology and dispersion stability in molten polyolefins.
Q4: What are the recommended storage conditions?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from direct sunlight and frost; avoid prolonged exposure to elevated temperatures or humidity to maintain dispersion integrity and viscosity stability.
Q5: Does this paste contain heavy metals or halogenated compounds?
A: Hostafine Red F5RK 30 is manufactured without intentionally added heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) or halogenated solvents, aligning with Clariant’s commitment to sustainable and restricted-substance-free pigment formulations.
