Q1: What is the primary application field for Hostatint Oxide Green CO 531 VP 6012?
A: This pigment paste is specifically developed for coloring polyolefin compounds—especially polypropylene (PP) and polyethylene (PE)—in applications requiring high thermal stability, good dispersion, and consistent green shade reproduction, such as automotive interior parts, technical components, and durable consumer goods.
Q2: Is this color paste suitable for food-contact or medical-grade polyolefins?
A: Hostatint Oxide Green CO 531 VP 6012 is formulated to meet stringent regulatory expectations for indirect food contact applications in polyolefins, subject to final formulation validation and compliance with applicable regional requirements. It is not intended for direct food-contact or medical device use without full regulatory assessment by the end-user.
Q3: How should this paste be incorporated into polyolefin compounds?
A: It is typically introduced via masterbatch dilution or direct addition during compounding—using twin-screw extrusion—with recommended melt temperatures between 180 °C and 240 °C. Good mechanical mixing and sufficient residence time ensure optimal dispersion and color development.
Q4: Does this product contain heavy metals or halogens?
A: Hostatint Oxide Green CO 531 VP 6012 is based on iron oxide pigments and is free from regulated heavy metals such as lead, cadmium, mercury, and hexavalent chromium. It contains no intentionally added halogenated compounds and is compatible with halogen-free material specifications.
Q5: What is the typical dosage range for achieving standard green intensity in PP?
A: Dosage depends on the desired shade strength and base polymer characteristics, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight in the final compound—to achieve full opacity and consistent hue.
