What is Polypropylene Copolymer?
To really understand how to make a plastic pen, you need to first become familiar with Polypropylene Copolymer or PPC. Used in everything from car parts to textiles, PPC was first discovered in 1951 by a pair of petroleum scientists named Paul Hogan and Robert Banks. This lightweight material has excellent physical and mechanical properties you won't find in any other plastic. For instance, it's completely stain resistant and has low moisture absorption.
