Polypropylene has a relatively slippery "low energy surface" that means that many common glues will not form adequate joints. Joining of polypropylene is often done using welding processes.
The properties of polypropylene depend on the molecular weight and molecular weight distribution, crystalline, type and proportion of co monomer (if used) and the isotacticity
