Machining Plastic Parts With Fluorosint 500 and 207

Fluorosint is a popular option for machining bearings, bushings, seals, shrouds, and hot air or steam applications. At Controlled Fluidics we offer plastics machining with both Fluorosint 500 and 207. A PTFE-based product, Fluorosint 500 offers a lower wear rate and a lower thermal expansion coefficient than PTFE. Fluorosint 207, in contrast, is more ductible but has a higher coefficient of expansion.

If you need help with designing a product, creating a prototype, or facilitating a full production run, let our 30+ years' of experience get the job done. We customize our efforts to meet the needs of our clients, and we can often turn around projects in four weeks or less.

We want your next project to be a success. Let's talk. Contact us at (603) 673-4323 or fill out the contact form to learn more about machining plastic parts with Fluorosint.

Fluorosint 500

The mica fill of this blend allows a very low coefficient of thermal expansion- approximately 40% of unfilled PTFE - along with a lower wear rate than PTFE. Its low coefficient of friction, good electrical properties and chemical resistance and form resistance to 650F make fluorosint 500 an excellent choice for bearings, bushings and other wear items.

Fluorosint 207

Although similar to the 500 grade, Fluorosint 207 has a lower mica fill level. The result is a more ductile material but a higher coefficient of thermal expansion. Fluorosint 207 is comparable to 25% glass filled Teflon with the benefit of being stronger and less abrasive. It is stable to 550F and thus is very good in hot air and steam applications.
