Fluoropolymer has a small friction coefficient, and good low friction properties.

Fluoropolymer has the smallest friction coefficient in all solid materials.

* ex. The dynamic friction coefficient of PTFE (polytetrafluoroethylene) is 0.1.
This great property are widely applied to the parts and equipment which can be used for powder sliders and sliding parts where lubricant is not used.

Fluoropolymer coating provides the solution

  • Prevent temporary stoppage due to blockage by powder bridges, etc
  • Prevent noise from knockers and damage to devices, and improve powder transport efficiency
