Durable Seals Designed for Lithium Battery Industry Needs

Product Description

High quality FKM seals for Lithium battery sealing industry

The fluorine rubber sealing rings produced by DEF Seals are widely used in the automotive and energy storage manufacturing fields. They have excellent high-temperature resistance, usually capable of withstanding temperatures ranging from -20°C to 200°C, and even higher. They also have good resistance to chemical corrosion, including acids, alkalis, solvents, and oils. Moreover, they possess sealing stability, with fluorine rubber typically having a long service life and maintaining its performance over long-term use without easily hardening or cracking. Additionally, they have electrical insulation properties: fluorine rubber has excellent electrical insulation, making it suitable for electronic and electrical applications. In terms of physical properties, fluorine rubber has outstanding tensile strength, tear strength, and wear resistance, making it very useful in sealing and vibration damping applications.
