PP (Polypropylene)
Polypropylene is a tough, flexible plastic used for most Bionicle weapons and minifigure parts that might break easily if they were a more rigid plastic. The plastic’s flexibility allows for it to be used as a “living hinge”, as in the book pictured here. Because it cannot be fully transparent, colors like 48 Transparent Green (pictured) look nearly opaque in PP, sometimes being mistaken for their solid counterpart color. PP often turns whitish along the edges as it wears. It is used for as varied applications as large buckets and pick-a-brick cups, and even the polybags that parts and small sets come in!
