Arnite has been selected for a variety of applications where tribological
(wear) characteristics are important. PBT displays good resistance to wear
loss and has low frictional coefficients, common to most semi-crystalline
thermoplastics. However, the outstanding frictional response of polyester to
rubbing contact with other materials is what sets PBT apart from other
thermoplastics. Real time frictional measurements comparing PA6 to PBT show
the excellent frictional consistency . For applications that require smooth
actuation as well as low overall frictional effort, PBT polyester is an
outstanding engineering material. Arnite PET is used in a variety of
applications where extreme wear requirements exists, e.g. where the static
friction coefficient should be as low as the dynamic one.
