Fluorosint® 500 a Sacrifice Gasket Material and More

Taking a Closer Look at Fluorosint® Materials
What Are the Advantages and Disadvantages of Fluorosint® 500?

Do you have a part where precision is highly critical and it will be under high pressure? Fluorosint® 500 could be just the material you need.

Fluorosint® 500 is a PTFE enhanced with a synthetic mica. This enhancement means more  opportunities to improve efficiency without sacrificing wear resistance. It also makes an excellent sacrificial wear surface that can help to prevent catastrophic system failures.

In testing there are a few things that really stand out about this material. One is it’s CLTE (in/in/˚F) of 2.5×10-5. Fluorosint® 500 is also 1/3 harder than PTFE and it also has a deformation under load of just 1.10%, that is 9 times lower than virgin PTFE. In fact, the overall performance of Fluorosint® 500 is similar to that of aluminum. Lastly, this material has very low frictional properties so it mates very well with many other materials.

Does this have you thinking about how you might use Fluorosint® 500? Here are a few of the most common uses. If you know of more – drop a comment on our blog!
• Split and one-piece seals
• Valve seats
• Shrouds
• Slide bearings
• Wear strips
• Sacrificial seals
• Abradable mating parts where the parts are allowed to “cut” their own running clearance
• Thrust washers
• A replacement for metal or aluminum seals and shrouds in compressors

To sum it all up – Fluorosint® 500 by Quadrant Engineering Plastics can be another great option to keep in mind if you need a material for a high load applications. It can have  some clear advantages over virgin PTFE and, like other PTFEs it possess chemical resistance. The next time you have a demanding application it maybe worth a look!
