igus iglidur I180 – High-Temperature Tribo-Polymer

iglidur I180 is igus's high-temperature tribo-polymer: self-lubricating, wear-optimized and rated for continuous operation up to 180 °C. No robust RoHS/REACH/FDA evidence on file; the SDS notes to avoid food contact. For plain bearings, bushings and guides in motor-adjacent, hot environments – where I150 is thermally overwhelmed.

Material Profile

iglidur I180 extends the iglidur concept (self-lubricating tribo-polymer) into the high-temperature range. While I150 is rated up to 90 °C, I180 bridges the thermal gap toward high-performance polymers like PEEK.

Use Case: Engine Bay Plain Bearing

In a conventional mechanical engineering approach, plain bearings for 150 °C environments would be made from bronze or PEEK – expensive, heavy, no self-lubricating function. With iglidur I180, a directly printed, maintenance-free part is produced in ~2–4 hours:

  • No post-processing (grinding, honing) at normal print quality
  • Integration of assembly features (screws, clips) possible
  • Rapid iteration: bearing geometry changed and reprinted in 4 hours

Application Limitation: No Food Contact

The safety data sheet (SDS) for iglidur I180 contains the note: “Uses which should be avoided: direct contact with food.” No FDA 21 CFR or EU 10/2011 evidence exists for this material. A separate material evaluation is required for high-temperature applications involving food contact.
