Glossy Tubes and Pipes
Tubes and pipes and methods of forming the same are described herein. The tubes and pipes include a wall structure having an external surface and an internal surface defining an internal chamber, said wall structure including at least one layer including a metallocene produced polyethylene resin and having an external surface having a gloss of at least 40 as determined by the standard test of ASTM D2457-90.
1 - 12 . (canceled)
13 . A tube or pipe comprising:
a wall structure having an external surface and an internal surface defining an internal chamber, said wall structure comprising at least one layer comprising a metallocene produced polyethylene resin and having an external surface having a gloss of at least 40 as determined by the standard test of ASTM D2457-90.
14 . The tube and pipe of claim 13 , wherein the metallocene-produced polyethylene has a density of from 0.910 g/cm 3 up to 0.966 g/cm 3 , and a melt index, M12, of from 0.001 to 20 g/10 min.
15 . The tube and pipe of claim 13 , wherein the metallocene-produced polyethylene has a density of 0.915 g/cm 3 to 0.940 g/cm 3 and a melt index, M12, of from 0.5 g/10 min. to 2.5 g/10 min.
16 . The tube and pipe of claim 13 , wherein the metallocene-produced polyethylene has a molecular weight distribution of from 2 to 7.
17 . The tube and pipe of claim 13 , wherein said wall structure is formed of a single layer.
18 . The tube and pipe of claim 13 , wherein said wall structure comprises a second disposed internal surface of said at least one layer.
