Q1: What is the primary application field for Hostafine Yellow SP-GR 30?
A: Hostafine Yellow SP-GR 30 is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers, where high thermal stability and good dispersion are required during extrusion or injection molding.
Q2: Is this color paste suitable for food-contact applications?
A: Yes, Hostafine Yellow SP-GR 30 is formulated to comply with global regulatory expectations for indirect food contact in polyolefins, subject to final formulation validation and adherence to applicable regional requirements.
Q3: How should this paste be incorporated into polyolefin compounds?
A: It is typically added directly to the polymer melt during compounding using standard twin-screw extruders. Good pre-mixing with a portion of the base resin is recommended to ensure uniform distribution and optimal pigment utilization.
Q4: What is the typical dosage range for achieving strong yellow shades?
A: Dosage depends on the desired shade intensity and base polymer opacity, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the total compound.
