PS Masterbatch
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.

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.
