1. Product Description & Characteristics

AdCol MB-BLK40-AG is an extrusion-grade polyethylene masterbatch carrying 40% fine-particle, high-surface-area furnace carbon black (P-type). Specifically engineered for micro-irrigation drip tubes, HDPE conduits, and UV-stabilized agricultural mulch films. Delivers exceptional macro-dispersion (ISO 18553), high thermal resistance, and uniform surface smoothness without screen-pack choking.
