Q1: What is the primary application field for Hostafine Red SP-FGR?
A: Hostafine Red SP-FGR is a high-performance organic pigment paste specifically developed for coloring polyolefin compounds—especially polypropylene (PP) and polyethylene (PE)—in applications such as fibers, tapes, injection-molded parts, and thin-walled packaging where excellent dispersion, thermal stability, and color consistency are required.
Q2: How does SP-FGR differ from other Hostafine Red pastes?
A: SP-FGR is formulated with a specialized carrier system optimized for polyolefins, offering enhanced melt compatibility, reduced plate-out tendency, and improved rheological behavior during compounding. Its pigment grade delivers higher tinctorial strength and better heat stability above 260 °C compared to standard grades intended for lower-temperature processing.
Q3: What is the recommended dosage range for optimal performance?
A: Dosage depends on the desired shade intensity and final application requirements, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in the polymer matrix. For deep red shades in PP fibers or thin films, lower dosages often suffice due to its high pigment loading and efficient dispersion.
Q4: Is Hostafine Red SP-FGR suitable for food-contact applications?
A: Hostafine Red SP-FGR is designed for industrial and technical applications and is not pre-qualified for direct food-contact use. Customers requiring compliance with food-contact regulations must conduct full formulation-specific testing and validation in accordance with applicable regional regulatory frameworks.
