Many people mistakenly call our products Rubber Band Belts because
they stretch like rubber. However, the term "Rubber Band Belt"
is incorrect for the following reasons:

in the upper right corner.
- "Rubber Band Belts" are made out of urethane,
which has elastic properties far superior to rubber.
- When stretched, rubber bands typically lose their
elastic properties quickly -- often with a few months. That is
why rubber conveyor belts are usually bonded to plastics
like urethane, pvc or nylon, and/or reinforced with fabric or
cords made from nylon, polyester or Kevlar
- Urethane bands last much longer rubber bands. Rotating
urethane belts can last 10 years or more, while static urethane
bands can last 15 years or more and still maintain elastic tension.
(Incidentally, our belts can be turned into round
or flat urethane bands. To make flat urethane bands we simply
slit our flat belts into narrow bands, e.g. 3/16" wide.)
- Urethane is also much more abrasive resistant than rubber,
so it will take much more abuse.
That is why virtually all "rubber band belts" are made out
of urethane, so they should be called urethane belts. For information
