Description

This material is internally lubricated. Formulations are specifically designed to be self-lubricating materials (PTFE), offering low coefficient of friction and improved wear-resistance properties. The key features are:


  • Excellent wear resistance
  • Reduced friction, heat buildup, and noise & vibration
  • Improved processability & surface finish on parts
  • Lower power requirements
  • Low maintenance
  • Design flexibility
  • Reduced weight
  • Properties
