Fluororubber
sealing, reinforced seal, "O" ring
Fluororubber sealing, reinforced seal
Fluororubber is a kind of high molecular elastomer
whose carbon atom of main chain or side chain contains fluorine
atom, and which could be sulfurated. Due to its own characteristics
of composition and structure, this elastomer is a kind of excellent
elastic materials, widely used in aeronautic, automobile, ship,
machinery, chemical, and light industry.
Properties: high resistance to heating, high
chemical stability, and excellent mechanical property (including
resistance to abrasion), resistance to atmospheric aging, satisfactory
dielectric property, fire resistance. Among all ever-used elastomers,
fluororubber is the one that has best resistance to heating and
chemical stability. It overcomes poor property of mechanical sealing
of polytetrafluoroethylene and instability of ordinary rubber.
Products: fluororubber 26B, G, fluororubber
246G, B and fluororubber TP, reinforced seal of all kinds of specifications,
¡°O¡± ring and other sealings.
