HIGH TEMPERATURE BLACK PERFLUOROELASTOMER

Z1319 Is the ultimate "next-generation" perfluoroelastomer offering a combination of excellent chemical resistance and ultra-high temperature stability, extending the operating limits in all aspects.

Z1319 has been specially formulated to provide increased resistance to a broad range of chemicals by controlling the molecular architecture. In addition, this perfluoroelastomer has low permeability and as a result, it is less prone to swelling, resulting in a higher service life.


FEATURES AND BENEFITS

  • Very high temperature resistance
  • Excellent chemical resistance to a wide range of chemicals
  • Exceptional acid and amine resistance
  • Superior mechanical properties
  • High sealing efficiency
  • Extremely low out-gassing properties
  • Excellent steam resistance (ASME BPE 2000)


APPLICATIONS

  • High temperature areas in the semiconductor manufacturing
  • Jet engines
  • Diesel engines
  • Pumps, valves and mechanical seals
  • Chemical industry
  • Oil and gas equipment

Compression Set Testing - ISO 815 B, 'cold-set'

  • Compression set testing performed when samples are cooled within the fixture prior to removal and measuring.
  • FFKM compounds are notoriously poor in this test.
