S<strong>of</strong>t Cut Gaskets<br />
Compressed Asbes<strong>to</strong>s Fiber<br />
(CAF) gaskets served industry’s<br />
needs for many years. With <strong>the</strong><br />
shift <strong>to</strong> Comrpessed Fiber gaskets,<br />
gasket manufacturers have<br />
developed a myriad <strong>of</strong> replacement<br />
products. Some <strong>of</strong> <strong>the</strong> initial<br />
materials developed proved<br />
inferior <strong>to</strong> <strong>the</strong>ir asbes<strong>to</strong>s based<br />
predecessors in regard <strong>to</strong> temperature,<br />
chemical resistance, creep<br />
resistance and sealing characteristics.<br />
More recently Flexitallic has<br />
developed compressed fiber gasket<br />
sheet products approaching,<br />
and in some instances surpassing<br />
<strong>the</strong> capabilities <strong>of</strong> asbes<strong>to</strong>s sheet<br />
gaskets. Some <strong>of</strong> <strong>the</strong>se products<br />
have been fiber reinforced grades, manufactured by <strong>the</strong> traditional calendering or sheeter process. O<strong>the</strong>r<br />
product ranges are fiber-free and some <strong>of</strong> <strong>the</strong>se materials have exceptionally good properties which exceed<br />
<strong>the</strong> capabilities <strong>of</strong> CAF.<br />
Flexitallic Thermiculite is a versatile gasket material based upon <strong>the</strong> exfoliated vermiculite mineral. The<br />
product is available with a metal reinforced core or coreless and is designed for use at temperatures which<br />
exceed <strong>the</strong> capability <strong>of</strong> graphite based sheets. The temperature capability <strong>of</strong> CAF is also exceeded by<br />
Thermiculite.<br />
The Flexitallic Sigma range <strong>of</strong> biaxially orientated PTFE products has superb chemical resistance, far<br />
exceeding that <strong>of</strong> CAF. These materials can be used at temperatures from cryogenic <strong>to</strong> 260°C (500°F).<br />
Being intrinsically clean <strong>the</strong>y are especially suitable for use in <strong>the</strong> food, pharmaceutical and electronics<br />
industries.<br />
Flexicarb is <strong>the</strong> name given <strong>to</strong> Flexitallic’s range <strong>of</strong> graphite based products. The range includes graphite<br />
foil as well as graphite laminates which contain reinforcing metal cores <strong>to</strong> overcome <strong>the</strong> fragility <strong>of</strong> <strong>the</strong><br />
non-reinforced foil. Graphite products have excellent stress retention properties and are resistant <strong>to</strong> most<br />
chemical media with <strong>the</strong> exception <strong>of</strong> strong oxidizing agents. Reinforced Flexicarb sheets are <strong>the</strong> standard<br />
sealing product for many arduous applications in <strong>the</strong> petrochemical and refining industries.<br />
The Flexitallic SF product ranges are rubber bound, fiber reinforced sheets made by <strong>the</strong> traditional calendering<br />
or sheeter process. A wide range <strong>of</strong> fiber types are used, <strong>of</strong>ten in combination, ranging from cellulose,<br />
rockwool and glass <strong>to</strong> aramid and carbon.<br />
S<strong>of</strong>t cut gasket sheets are typically used in Class 150 or Class 300 flanges. The temperature capability <strong>of</strong><br />
<strong>the</strong> fiber/rubber products is highly thickness dependent, with thin gaskets having a wider service envelope<br />
than thicker ones.<br />
