WebAmorphous polymers always show elastic properties and also form cross-linkages. Amorphous polymers are soft usually due to long-ranged coordination. The behavior of amorphous polymers is that they become soft slowly as the temperature increases. Amorphous polymers have less dimensional stability and it can easily deform. WebIs it a bearing and/or wear application? Wear properties are enhanced by MoS 2, graphite, carbon fiber, and polymeric lubricants (PTFE, waxes).For bearing and wear applications, the first consideration is wear performance expressed in PV and k-factor.Calculate the PV (pressure (psi) x velocity (m/min)) required.
