PTFE special CompoundSUMIKASUPER® S300

Sumika Super S300 is resin where PTFE is added with Sumika Super E101, and demonstrates superior sliding properties. Poor wear resistance and compression creep characteristics which are demerits of PTFE have been remarkably improved in Sumika Super S300, while maintaining low wear coefficient of PTFE.
It is mainly used for sliding parts, bearings, bushes and washers.


  • Sliding parts
  • Bearings
  • Bushes
  • Washers and others

  • Industrial machine related parts

  • Food manufacturing related parts

Features and Merits

❶ The improvement in sliding properties reduced abnormal noises and motor load.

Sumika Super S300, owing to its superior sliding properties, is employed for bushes used for metal etchers by a semi-conductor manufacturing devices.

Applications Bushes for the metal etcher of semiconductor manufacturing devices.
