DOW™ MDPE NG 7525 Medium Density Polyethylene Resin

MDPE NG 7525 is a Medium Density Polyethylene Resin produced in the UNIPOL™ Process. This resin is recommended to be used in thin-wall micro-irrigation tape application and profile extrusion application. Resin exhibits good draw down characteristics producing tapes with a reliable balance of extrusion and stiffness. It can also be used as a component in mixtures with low density polyethylene resins and linear low density polyethylene resins, to modify and improve the mechanical properties. Outdoor applications require the addition of UV stabilizer to maintain the excellent properties over extended periods of UV exposure.
