Perlast G65HP

Perlast® G65HP has a unique organic formulation developed specifically for critical semiconductor processes where the seals are in direct contact with plasma. This new material grade provides excellent plasma resistance in high concentration radical fluorine plasma, as well as other plasma chemistries.

  • With a 100% organic structure, Perlast® G65HP minimizes the risk of particle generation
  • Fewer than 10k parts per billion trace metal content
  • Excellent fluorine, chlorine and oxygen plasma resistance
  • Excellent generic chemical resistance
  • Very low risk of particle generation
  • Good mechanical properties
  • Low out-gassing properties


  • Extended maintenance cycles.
  • Ideal for manufacturers of devices at advanced technology nodes
  • Ensure the integrity of device electrical specifications
  • Minimal reliability failures
