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.
