This material is a higher molecular weight material than the standard HDPE. The material displays improved performance characteristics in a variety of piping applications. In addition, the material is UV stabilized and ideal for use in demanding outdoor applications. It retains its properties between -220°F and 180°F and resists most chemicals. It is also NSF certified under Standard 61 to be used in potable water piping systems. HDPE Pipe Grade can be used in a variety of applications including manhole lids and bottoms, pipe reducers, trenches, sumps, pipe flanges, pipe end caps, tanks, milled flange adapters and lifting lugs.
