MATERIAL - PARKER FF200-75
FF200-75 is Parker’s ULTRA™ FFKM Material for AMS 7257 Aerospace Applications and is part of Parker's ever growing family of FFKM compounds.
Formulated to provide ultimate sealing, these compounds handle continuous exposure to high temperature, provide near universal chemical compatibility, have high sealing force retention, low compression set and outstanding mechanical properties.
Aerospace applications for AMS 7257 material are characterised by severe high temperatures and intricate and varied media environments. The AMS 7257 specification establishes a baseline for elastomeric materials considered capable of withstanding long term exposure to 550°. When the operating environment demands extreme sealing performance, customers often specify a material that exceed the AMS 7257 standard. ULTRA FF200 exhibits superior retention of mechanical properties and resistance to compression set after long term high temperature and fluid exposure. FF200 accomplishes this without the cost penalty normally associated with performance enhancements.
Typical Applications:
- Gas turbine engine lubrication systems
- Bleed air management and ducting systems
- High temperature propulsion units and their associated control devices utilizing NTO, MMH, JP4 and other strong oxidizers/propellants
- Any environments in which high heat and aggressive chemistries are present
Features:
- High temperature range up to 608°F
- Low compression set
- High seal force retention
- Fluid compatibility
