PTFE is modified with a filler material to create these impact-resistant rods. They have a super-slippery surface that resist wear, as well as excellent resistance to chemicals and extreme temperatures. These easy-to-machine rods are nonabsorbent, so they won’t swell when exposed to water. They’re also good electrical insulators.
Grade 641 is often used to fabricate bearings and pump parts.
