An Informational Brief on Polymer Machining Polytetrafluoroethylene (PTFE) is a fluorocarbon-based polymer, known more commonly as Dupont's brand name Teflon®. The enhanced electrical properties, high-temperature capabilities and chemical resistances of this thermoplastic make it a favorite for backup rings, coatings, distribution valves, electrical insulation applications and more.To get more news about machining teflon, you can visit runsom.com official website. Read on to learn more about Teflon's machining, applications and properties in AIP's informational polymer brief below, starting with the difference between working with a thermoset and a thermoplastic. Properties & Grades of Machined Teflon Unfilled PTFE is chemically inert and has the highest physical and electrical insulation properties of any Teflon grade. Mechanical grade PTFE is often made up of reground PTFE and exists as a cost-effective alternative for industries that don't require high purity materials while providing superior compressive strength and wear resistance to virgin Teflon. There are several different modified PTFE materials available with unique properties. Many of these modified grades offer greatly reduced deformation percentages under load, as well as a lower coefficient of friction. These include glass-filled, nanotube, synthetic mica and carbon-filled grades. Teflon (PTFE) is more commonly used as an additive to numerous other base polymers in order to provide reduced friction and wear properties. |
