Simriz® 501 is a compound that was developed by Freudenberg as the next-generation material to the well-known Simriz® Z7257. Simriz® 501 is specially designed for the aerospace industry by far exceeding the requirements of AMS7257 thanks to its exceptional temperature resistance of up to 617°F (325°C) and a broad range of harsh chemical environments including:
- Strong inorganic and organic acids
- Steam and water
- MIL-PRF-23699 HTS turbine lubricants after these lubricants start to degrade
How do you know Simriz® 501 is a quality material?
Freudenberg has performed extensive testing including flight testing in high-temperature aerospace applications that verify that it not only surpasses AMS7257 requirements but also outperforms competitive materials in O-ring compressive stress in customer testing.
Typical applications
- Bleed Air Management Systems
- Gas Turbine Lubrication Systems
- High-Temperature Propulsion Units
- Control Devices utilizing strong oxidizers
