The effects of copper and polytetrafluoroethylene (PTFE) on thermal conductivity and tribological behavior of polyoxymethylene (POM) composites 

Polyoxymethylene (POM) is a resistant polymer with wide applications in aerospace, automotives, and biomedicine. However, it falls short when used in the manufacturing of sliding parts. In this study, copper particles and polytetrafluoroethylene (PTFE) powder were incorporated into POM to improve the thermal conductivity of the polymer composite while reducing the friction coefficient. A thermal analyzer was used to measure the thermal conductivity of POM composites using the transient plane ...

Thermal conductivity and tribological properties of POM-Cu composites

Polyoxymethylene (POM) composites were prepared by using varying concentrations of copper particles and tested thermally via tribologically via an M-2000 friction and abrasion testing machine. A copper concentration below 10 wt.% didn't affect the thermal properties of the POM composite but using higher concentrations resulted in improved thermal conductivities. Using a copper concentration of 25 wt.% resulted in a thermal conductivity value 35.9% higher than unfilled POM. In addition to the improved thermal ...
