PTFE Extruded Rod

PTFE Extruded Rod is now manufactured here at CIP

PTFE Rod is known as having the lowest co-efficient of friction of any solid material and is extremely effective operating at extremely high and low temperatures.

What is PTFE?

PTFE (Polytetrafluoroethylene) fluorocarbon resins represent one of the most versatile products lines ever to emerge from Du Pont laboratories. From Exotic space-age applications to molded parts and wire and cable insulation to its consumer use as a coating for cookware, PTFE has fulfilled a wide variety of roles in its 40-year history.

PTFE in Chemical Service

PTFE (Polytetrafluoroethylene) fluorocarbon resins represent one of the most versatile products lines ever to emerge from Du Pont laboratories. From Exotic space-age applications to molded parts and wire and cable insulation to its consumer use as a coating for cookware, PTFE has fulfilled a wide variety of roles in its 40-year history.

One of its largest and fastest growing uses today is for corrosive protection. This use is attractive because PTFE resins are chemically inert to almost all industrial chemicals and solvents. This nearly universal chemical inertness stems from three characteristics of PTFE molecule: (1) the very strong interatomic bonds between carbon and fluorine atoms; (2) the almost perfect shielding of the polymers carbon backbone by fluorine atoms; and (3) the very high molecular weight (or long polymer chain length) compared to many other polymers.

There are three members of the family of PTFE resins:

PTFE TFE resin–the original PTFE resin invented by Du Pont in 1938. Normally it is an opaque, white material. When melted it does not flow like other thermo plastics and must be shaped initially by techniques similar to powder metallurgy. Maximum continuous service temperature is 260°C.

PTFE FEP resin was also invented by Du Pont and became a commercial product in 1960. It is a true thermoplastic that can be melt extruded and fabricated and is transparent in thin sections. It eventually becomes translucent as thickness increases. Maximum continuous service temperature is 205°C.

PTFE PFA resin – introduced in 1972, has excellent melt-processability and properties rivaling or exceeding those of TFE. PFA permits conventional thermoplastic molding and extrusion processing at high rates and also has higher mechanical strength at elevated temperatures. Maximum continuous use temperature is 260°C.

The use of PTFE in chemical processing equipment began in the late 1940’s. The early applications were gaskets and valve packing’s, valve diaphragms and mechanical seals. These led to the development of linings of pipes, valves, pumps and vessels, hence completely lined chemical processing systems. The liner developments were aided considerably by the advent of the melt-processable PTFE FEP resins and film. The new melt-processable PTFE PFA resin is proving to be valuable addition in broadening the many chemical uses of PTFE. Descriptions of typical applications for fabricated forms of these resins are appended. From these we see that the resistance of PTFE to both high temperatures and corrosive chemicals is providing solutions to many of the more difficult problems in chemical processing today.
