Product Description:
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.
Features:
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.
