Solstice® PF-HP

Cleanliness Verification Solvent

Solstice® PF-HP (High Performance) is an ultra-clean, highly-effective, nonflammable cleaning solution with desirable safety and environmental attributes. It is ideally suited for oxygen system cleaning for propulsion and life support in commercial aircraft, military, and spacecraft applications.

Based on hydrofluoro-olefin (HFO) technology, Solstice® PF-HP will effectively remove contamination from the desired lines or parts and then be completely dried leaving no residues behind. The vapor pressure of Solstice® PF-HP facilitates quick evaporation and drying of cleaned materials.

  • Excellent cleaning and quick drying
  • Non-volatile residue (NVR): < 2 ppm
  • Good stability and materials compatibility
  • NASA approved (preferred replacement for AK 225G in oxygen system cleaning)
  • Contains no stabilizers or additives, which can contribute to NVR
  • Replacement for HFE, IPA, HCFC, HFC, TCE, nPB, and other solvents
  • No REACH SVHC
