Plastic Machining with Fluorosint 500 and 207 Plastic

Pete Poodiack, VP of Sales and Marketing at Controlled Fluidics, talks about Fluorosint 500 and 207 plastic and what makes it a popular material for plastic machining and fabrication.

Welcome, In this video, we’re talking about Fluorosint 500 and 207. These are great materials with good wear resistance, and they can handle continuous operations of up to 500 degrees Fahrenheit. They also have a chemical resistance level that is very close to PTFE so they end up appearing in similar applications — At Controlled Fluidics, we find that a lot of our clients end up choosing between PTFE and Fluorosint for their projects.

So, let’s talk about the differences between the 500 and the 207. Well, Fluorosint 500 has good electrical properties along with chemical and form resistance. It features a mica fill that allows a very low coefficient of thermal expansion as well as a low coefficient of friction. That makes it a popular choice for bearings, brushings, and similar items that are in high-wear environments. Compared to PTFE, Fluorosint 500 has a lower wear rate, and its thermal expansion is approximately 40% of unfilled PTFE.

Now, let’s look at Fluorosint 207. This is very similar to Fluorosint 500. It has a lot of the same benefits, but it has a lower mica fill level. That makes it more ductile with a higher coefficient of thermal expansion. It’s actually pretty comparable to 25% glass-filled Teflon, but it’s less abrasive and stronger than Teflon. The 207 is also stable in temperatures of up to 550 degrees Fahrenheit, and that’s why at Controlled Fluidics, we see this material used for a lot of hot air or steam applications.
