The co-extruded color layer provides a full exterior color appearance
Color layer is made from same HDPE as inner wall – performance properties are unaffected
Total wall thickness = inner black wall thickness + external color layer thickness
Conduit dimensions meet or exceed the requirements of ASTM F-2160 for the wall type selected
The black inner wall has a minimum of 2% carbon black per condition C of ASTM D-3350
Co-extruded color layer has UV stabilizers and antioxidants per condition E of ASTM D-3350
Color fastness and UV protection performance for co-extruded conduit is equal to full wall colors and is suitable for storage outdoors for up to one year
