RIGIDITY AND DENSITY When making a part out of polyurethane, the first two properties to consider are usually rigidity and density. Rigidity, which correlates somewhat with durometer (hardness), is mostly determined by chemical composition, and can be anywhere from that of the hard plastic shell of ...

URETHANE FOAM Foaming, or blowing, offers several potential advantages for polyurethane parts. You can "fill" the same volume with less material, so the part is lighter and it costs less, while still maintaining most of its structural integrity. You can make parts light in the first place, if that's...
