TUWE Black Masterbatch is a high-performance color concentrate formulated primarily for polypropylene (PP) resins. Presented as uniform black granules, it delivers consistent, deep black coloration while meeting stringent technical requirements. Engineered for versatility, it is suitable for both standard and flame-retardant applications across various industries, including automotive, electronics, and consumer goods. The masterbatch is designed for excellent dispersion and compatibility within PP matrices.
Superior Stability: Low volatility (≤0.3%) ensures minimal fuming during processing, enhancing workplace safety and equipment cleanliness.
High Thermal Resistance: Withstands processing temperatures exceeding 240°C (thermal decomposition temperature ≥240°C), making it suitable for high-temperature extrusion and injection molding.
Exceptional Purity & Consistency: High active content (88-90%) and reliable color strength, batch-to-batch consistency, and minimal contamination risk.
Effective Flame Retardancy: Enables PP compounds to achieve the stringent UL94 V-0 flammability rating (at 1.6mm thickness) when incorporated at recommended dosage levels.
Optimized Performance: Maintains or minimally impacts key mechanical properties of the base PP resin (tensile strength, impact, elongation, flexural strength, HDT).
Ease of Use: Granular form ensures easy handling, storage, and accurate dosing during compounding or direct injection molding.
