Q1: What is the primary application area for Hostafine Brown HFR 30?
A: Hostafine Brown HFR 30 is specifically developed for coloring polyolefin-based packaging materials, including flexible films, rigid containers, and injection-molded closures—especially where high thermal stability and low extractables are required during processing.
Q2: Is this color paste suitable for food-contact applications?
A: Yes, Hostafine Brown HFR 30 is formulated to meet global regulatory expectations for indirect food contact in polyolefins, subject to compliance with applicable regional requirements and proper end-use validation by the compounder or converter.
Q3: How should Hostafine Brown HFR 30 be incorporated into polyolefin compounds?
A: It is typically added via masterbatch dilution or direct gravimetric dosing during compounding. Good dispersion is achieved using standard melt-processing equipment; pre-drying is not required, but storage under dry, cool conditions is recommended to maintain consistency.
Q4: What level of heat stability does this paste offer during polyolefin processing?
A: Hostafine Brown HFR 30 exhibits excellent thermal stability up to typical polyolefin processing temperatures (e.g., extrusion and injection molding), minimizing color shift or degradation under standard residence times and shear conditions.
Q5: Can it be used in combination with other Hostafine pigments or additives?
A: Yes, Hostafine Brown HFR 30 is compatible with other Hostafine color pastes and common polyolefin additives—including antioxidants, slip agents, and antistats—provided compatibility is confirmed through formulation trials under intended processing conditions.
