Q1: What is the primary application field for HOSTAJET YELLOW 4G-PT?
A: HOSTAJET YELLOW 4G-PT is specifically developed for coloring polyolefin-based packaging films and containers, especially where high thermal stability and excellent dispersion are required during extrusion or injection molding processes.
Q2: Is this color paste suitable for food-contact applications?
A: Yes — HOSTAJET YELLOW 4G-PT is formulated with pigments and carriers compliant with global food-contact regulations for polyolefins. Final compliance depends on the full formulation, processing conditions, and regional regulatory requirements.
Q3: How should HOSTAJET YELLOW 4G-PT be incorporated into polyolefin compounds?
A: It is typically added directly to the polymer melt using gravimetric or volumetric dosing systems. Good mixing efficiency is achieved at standard extrusion temperatures, and it disperses readily without requiring pre-dilution or masterbatch dilution in most cases.
Q4: What is the recommended dosage range for optimal coloration?
A: Dosage depends on the desired shade intensity and base resin properties, but typical usage generally ranges from 0.1% to 2% by weight relative to the polymer. Lower concentrations often suffice due to its high chroma and efficient pigment loading.
Q5: Does HOSTAJET YELLOW 4G-PT offer resistance to migration during storage or end-use?
A: Yes — it exhibits low tendency toward pigment migration under normal storage and service conditions, thanks to its optimized carrier system and strong pigment-polymer compatibility in polyolefins.
