Material type

Hey, wanted to ask for some help/opinions for a project. Making and aluminum cable holder for outside project, and wanted to line inside of holder with removeable-molded polypropylene.
The mold would be C shaped, about 1 inch wide and 2 inch tall (probably a groove to reduce slipping)... The cable it will hold is PVC lined... Needs to have UV protection, and somewhat resistant to PVC friction.
What type of Polypropylene would you recommend, and any shops you would recommend as well. I wanted to be somewhat fluent in need when calling some wanted to get your expert opinions first.
Thanks!!
