Masterbatch for PET Bottle and Preform Production
Our Masterbatch is formulated for PET bottle and preform applications. It functions as a polymer coloring agent that delivers consistent color throughout the preform and final bottle. The product is designed to work with PET resin for injection molding preforms followed by blow molding. Color dispersion is uniform and clean with no visible specks or unmelted pigment spots. This helps bottle makers avoid rejects caused by uneven appearance or dark spots in the finished bottle. The carrier resin is compatible with PET so crystallization behavior and final clarity stay intact.
This Masterbatch version handles the specific demands of preform injection molding lines. Our colorant maintains good flow characteristics at typical injection temperatures for PET. We select pigments that are fine enough to disperse evenly without acting as nucleating agents that cause haze. This matters for water bottle and carbonated drink producers where clarity…
