1031 is a bronze and molybdenum disulfide
filled PTFE (polytetrafluorethylene) material. Due
to the higher thermal conductivity of bronze, this
material dissipates heat substantially faster than
unfilled PTFE. It thus exhibits excellent tribological
properties at higher speeds in dynamic applications.
Deformation under load is also improved due to the
bronze content. Since some harsh chemicals attack
bronze, use in corrosive environments must be carefully
examined.
