POLYURETHANE VS STEEL • Density: 7500kg/m3 vs 1200kg/m3 (6 times lighter than steel)

o Safe to work with

o Easy to cut and drill

• Noise Pollution (in an underground hopper):

o Empty hopper = 119dB

o Hopper with UT liners = 106dB

• Installation time:

o Customers claim up to a 50% reduction in installation time

o Female installers can also be used

• Inexpensive to customize liners (low pattern costs)

• Wear indicators are built into liners, improving preventative maintenance
