DOWLEX™ 2342M Polyethylene Resin is a high density ethylene/octene copolymer resin. It has a unique molecular structure with a linear polyethylene backbone and controlled octene side branches, which provides a combination of flexibility with very high toughness and stress crack resistance. A specified carbon black masterbatch is incorporated into the DOWLEX 2342M Polyethylene Resin during extrusion to arrive at a fully stabilised, homogeneous black sheet with excellent weldability. Sheeting thus produced meets the requirements of the Guidelines and Directives controlling general water barrier membranes such as the North Rhine Westfalia Guidelines or "Guideline for Plastic Membranes in Landfill sites" issued 7/92 from B.A.M. Berlin.
Processability: Typical extrusion temperature range for DOWLEX 2342M Polyethylene Resin is 190 to 230 °C. The resin contains processing stabilisers compatible with those in the Masterbatch added to guarantee short and long term processing, thermal and environmental stability including metal deactivators.
Applications:
Heavy sheeting.
General water barrier membranes.
