Products Description
FDA FFKM High-Temperature O-rings are special sealing ring products designed for high-temperature and high-demand occasions. They have the advantages of high-temperature resistance, chemical corrosion resistance, and compliance with FDA food hygiene standards. They are widely used in chemical, food, pharmaceutical, and other industries.
Advantages
- Applicable temperature range: It can be used at temperatures up to +325°C (617°F). Compared with traditional nitrile rubber or silicone rubber O-rings, these FDA FFKM high-temperature O-rings can withstand higher temperatures.
- FDA certification: This FFKM O-ring meets the requirements of the FDA (Food and Drug Administration) and is suitable for use in food, beverage, pharmaceutical, and other applications that require hygienic standards.
- Low particle and high purity: FFKM O-rings offer low particle and high purity options to meet high cleanliness requirements, especially for the semiconductor industry.
- Chemical resistance: FFKM material has excellent corrosion resistance to most chemicals and can be used in various chemical industries.
- Long life: FFKM O-rings have a longer service life than traditional materials and are suitable for long-term sealing applications.
