PTFE - Mechanical Sheet and PTFE - Rod

PTFE , polytetrafluoroethylene, more commonly known as PTFE, is one of the three fluorocarbon resins in the fluorocarbon class composed wholly of fluorine and carbon. The other resins in this group, also referred to as Teflon, are PFA and FEP and is reviewed under that heading. Mechanical PTFE material is more economical grade made up of 25% regrind PTFE so there may be some small amount of contamination that will not affect its physical properties but may affect its electrical dielectric properties.

The forces binding the fluorine and carbon together provide one of the strongest known chemical linkages in a compact symmetrical arrangement of atoms. The result of this bond strength plus the chain configuration is a relatively dense, chemically inert, thermally stable polymer.

PTFE material resists attack by heat and virtually all chemicals. It is insoluble in all organics with the exception of a few exotics. Its electrical properties are excellent. Although it has high impact strength, its resistance to wear, tensile strength and creep resistance are low in comparison to other engineering type thermoplastics. Mechanical properties can be improved by adding fillers such as glass fibers, bronze, Delrin, carbon, and graphite.

PTFE Rod, Sheet and Tube exhibits the lowest electric constant and lowest dissipation factors of all solid materials. Because of its strong chemical linkage, PTFE Sheet rod and tube shows very little attraction for dissimilar molecules. This results in a coefficient of friction as low as 0.05. Once again, because of this chemical bonding, PTFE resins are virtually insoluble.
