Polypropylene
>
> Polypropylene (PP) is a drocarbon polymer, expressed as
> CnH2n. PP, like polyethylene (see HDPE, L/LLDPE) and polybutene (PB),
> is a polyolefin or saturated polymer. Polypropylene is one of those
> most versatile polymers available with applications, both as a plastic
> and as a fibre, in virtually all of the plastics end-use markets.
