Q1: What is the primary application field for Hostaperm P2GL Color Paste?
A: Hostaperm P2GL is a high-performance organic pigment-based color paste specifically developed for demanding polyolefin applications, including injection-molded and blow-molded packaging, automotive interior parts, and technical components requiring excellent thermal stability and color consistency during processing.
Q2: Is Hostaperm P2GL suitable for food-contact plastics?
A: Hostaperm P2GL is formulated to meet stringent regulatory expectations for indirect food contact applications in polyolefins, subject to compliance with applicable regional requirements and final formulation validation. Users must verify suitability through their own regulatory assessment and migration testing under intended use conditions.
Q3: How does Hostaperm P2GL perform under high-temperature processing conditions?
A: This color paste exhibits very good thermal stability, maintaining color integrity and minimizing pigment degradation during standard polyolefin processing—such as extrusion and injection molding—at temperatures up to approximately 260 °C. Performance may vary depending on residence time, shear history, and polymer matrix.
Q4: What is the typical dosage range for Hostaperm P2GL in polyolefin compounds?
A: Dosage depends on the desired shade intensity and base polymer characteristics, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight—due to its high tinctorial strength and efficient dispersion in polyolefin melts.
