    Aging in PP

    Hi, Has anyone ever had problems with shelf-life in injection-molded PP parts? I'm looking at high flow PP, UV resistant PP, or metallocene PP and I would like a shelf-life of 2 years. Specifically interested in surface chemistry changes. Cheers!

    PP for small injection-molded part

    Hi, I'm trying to source an alternative resin for some small, injection molded parts. Has any one ever used a lumicene polymer? I have no experience with metallocenes so I'm trying to guess if there will be anything unusual about its surface chemistry or anything. Cheers!
