PS Masterbatch
Color Masterbatch for HIPS GPPS
Color masterbatches for GPPS (General Purpose Polystyrene) and HIPS (High Impact Polystyrene) provide precise, consistent coloration for these widely used styrenics. Key considerations include:
Low-Processing Temperature Compatibility: Must disperse effectively and color uniformly at typical GPPS/HIPS processing temps (180-250°C) without degradation or causing plate-out.
Optical Integrity (GPPS): Especially critical for transparent/translucent GPPS applications; pigments must avoid haze or clarity loss.
Impact Modifier Compatibility (HIPS): Must not interfere with HIPS's rubber toughening system or negatively affect mechanical properties.
Solvent/Migration Resistance: Essential for applications like food packaging, electronics, or medical parts exposed to chemicals.
Electrical Neutrality: Critical for components requiring specific dielectric properties. Excellent dispersion ensures aesthetic quality and performance.

Color Masterbatch for PS is a concentrated pigment blend specifically formulated for Polystyrene resins. It ensures vibrant, uniform coloration while maintaining PS's clarity (for transparent grades) and processing characteristics.
Key Features:
High Compatibility: Optimized carrier resin ensures excellent dispersion in PS, HIPS, and AS resins without compromising mechanical properties.
Thermal Stability: Withstands processing temperatures up to 280°C, preventing degradation during injection molding or extrusion.
Quality Consistency: Eliminates pigment dust, reduces contamination risks, and delivers spot-free coloration (no streaks or spots).
Specialty Grades: Includes options like pearlescent effects, UV resistance, and food-contact-compliant formulations.
Applications:
Consumer goods (toys, cosmetics containers)
Houseware products (cups, utensils)
Packaging materials
Industrial components.
Usage Guidelines:
Dosage: Typically 2–4% by weight, adjustable for opacity requirements.
Processing: Compatible with injection molding, extrusion, and blow molding.
This masterbatch streamlines production, enhances color accuracy, and reduces waste compared to raw pigments.
