Q1: What is Cabot UN2005 Masterbatch primarily used for?
A: Cabot UN2005 Masterbatch is a carbon black–based concentrate designed to provide consistent jetness, high tint strength, and excellent dispersion in thermoplastic polymers—particularly polyolefins such as PP and PE—used in demanding applications including packaging films, technical parts, and industrial containers.
Q2: Is Cabot UN2005 suitable for food-contact applications?
A: Cabot UN2005 is formulated with food-grade compliant carbon black and carrier resins. When compounded under appropriate manufacturing conditions and validated within the final application, it may be suitable for indirect food-contact uses; however, end-use compliance must be confirmed by the compounder or converter against applicable regional regulatory requirements.
Q3: How should Cabot UN2005 be incorporated into base resins?
A: It is typically introduced via standard gravimetric or volumetric feeding systems during extrusion or injection molding. Good melt mixing and adequate residence time are recommended to ensure uniform dispersion. Pre-drying is generally not required unless ambient humidity is exceptionally high or the base resin demands it.
Q4: Does Cabot UN2005 offer UV stabilization benefits?
A: While not a dedicated UV stabilizer, the carbon black in UN2005 contributes inherent UV absorption and protection to the polymer matrix. This helps reduce photo-oxidative degradation in outdoor or light-exposed applications—though additional stabilizers may be needed for long-term weathering performance depending on service conditions.
Q5: What is the typical dosage range for Cabot UN2005 in finished compounds?
A: Dosage depends on the desired color intensity, substrate transparency, and processing conditions, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the base polymer—to achieve optimal dispersion and performance without compromising mechanical properties.
