FFKM-Metal Composite Products
FFKM-Metal Composite Products
FFKM Metal Composite Products are high-end sealing and protective components made from Perfluoroelastomer (FFKM) combined with a metal substrate. They integrate the extreme chemical resistance and high-temperature elasticity of FFKM with the mechanical strength and dimensional stability of metal. These products are widely used in high-temperature, high-pressure, strongly corrosive media, and critical service conditions, effectively overcoming the limitations of using rubber or metal alone under extreme environments. They provide reliable prevention of liquid and gas leakage, extend service life, and reduce equipment maintenance costs.
Main characteristic
- Excellent Chemical Resistance: The FFKM layer resists almost all chemical media, including strong acids, strong alkalis, ketones, amines, esters, ethers, and strong oxidizers.
- Wide Temperature Range: Capable of stable long-term operation from -40℃ to +325℃.
- High Strength & Extrusion Resistance: The metal substrate provides strong mechanical support, preventing cold flow and creep of FFKM under high pressure.
- Superior Gas Tightness: Suitable for vacuum, ultra-pure gases, and applications requiring high sealing integrity.
- Extended Service Life: The composite structure of rubber + metal significantly enhances durability and reliability.
- High Customizability: Metal framework geometry and FFKM coating thickness can be tailored to different equipment designs.
Typical application
- Chemical Industry: Sealing for reactors, manholes, pumps, and valves under high-temperature, high-pressure, and corrosive conditions.
- Semiconductor Manufacturing: Key sealing components in plasma etching chambers, vacuum chamber doors, and ultra-pure transfer systems.
- Pharmaceutical & Bioengineering: Reliable seals for high-purity liquid transfer and systems exposed to aggressive disinfectants.
- Energy & Aerospace: Seats and sealing rings for fuels, electrolytes, and propellants under extreme media conditions.
