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.
