A versatile family of materials, castable
polyurethane elastomers has been used to produce the following articles:
gears, sprockets, heavy duty truck bushings, skateboard and in-line skate
wheels, mining sizing screens, energy-absorbing shoe soles, prototype parts,
business machine and paper mill rollers, etc.
Castable polyurethanes are elastomers. They are
available in a wide range of hardnesses and chemical compositions. Generally,
they are considered to have outstanding physical properties including
toughness, tear resistance, abrasion resistance, high load bearing capability,
and good chemical resistance, to name but a few.
Castable polyurethanes are liquid at their
typical process temperature of 150ºF. Therefore, they are usually processed
by pouring into an open mold. This castability offers several advantages to a
design engineer, including low mold cost as well as the ability to produce
large parts or parts with thick wall cross-sections. In addition to open
casting, these polyurethane materials may also be compression molded, spin
cast, and transfer molded for even greater processing versatility.
