Q1: What is the primary function of Cabot PE2718 Masterbatch in polyethylene applications?
A: Cabot PE2718 Masterbatch is a carbon black–based concentrate engineered to provide consistent jetness, UV stabilization, and electrical conductivity control in polyethylene compounds—particularly for packaging, geomembranes, and industrial films.
Q2: Is Cabot PE2718 suitable for food-contact polyethylene applications?
A: Yes—PE2718 is formulated using food-grade carbon black and carrier resins compliant with global regulatory expectations for indirect food contact. Final compliance depends on the full formulation, processing conditions, and applicable regional regulations.
Q3: How should PE2718 be incorporated into PE resin during compounding?
A: PE2718 is designed for standard melt-processing equipment—including twin-screw extruders—and disperses efficiently under typical PE processing temperatures (160–220 °C). Pre-drying is not required, but optimal dispersion benefits from adequate residence time and shear history.
Q4: Can PE2718 be used in both HDPE and LDPE systems?
A: Yes—PE2718 is compatible with a broad range of polyethylene grades, including HDPE, LDPE, LLDPE, and metallocene-catalyzed PE. Its carrier system ensures good compatibility and minimal viscosity impact across these matrices.
Q5: What is the typical dosage range for achieving target blackness and UV protection?
A: Dosage depends on the base resin, desired opacity, and end-use performance requirements—but PE2718 is typically used at low concentrations, generally ranging from 0.1% to 2% by weight, to deliver effective jetness and long-term UV resistance.
