TFE/ TFE-R

High temperature,chemically inert,heat-shrinkable tubing

Raychem TFE and TFE-R are heatshrinkable tubings manufactured from a modified Teflon (Polytetrafluoroethylene), an excellent high temperature covering and insulation material w ith a milk-w hite translucence. TFE is the general purpose tubing for difficult chemical and thermal environments. TFER has the added advantages of thin w all, high shrink ratio, greater flexibility and

transparency in application. TFE and TFER are highly flame retarded and exhibit outstanding chemical and solvent resistance w ith electrical characteristics which remain stable over a wide temperature range. The operating

temperature ranges from -67 ?C to +250 ?C, and up to 400?C for short

periods.

The major uses of these materials are for electrical insulation, protection of electronic components and the covering of hydraulic hose and couplings preventing contamination and corrosion. The high mechanical strength and extremely low coefficient of friction make it ideal for reducing damage to bearing shafts, etc.

The largest size w hich w ill recover snugly over the component to be covered should be ordered.

With TFE-R the maximum outside diameter of the device to be encapsulated should be less than 2 0%of the minimum expanded inside diameter of the tubing. The w all thickness of the tubing w ill be less than specified if recovery is restricted during shrinkage.

Other lengths and sizes are available subject to special order.

For full product performance details consult Raychem Specification TFE RW 205 5 TFE-R RW 2 05 4.

For optimum performance TFE and TFE-R must be heated above their crystaline melting points, 3 27?C. As the tubing reaches this temperature, it turns from a milk-w hite translucence to a completely transparent material - at this point the heat source should be removed, as 2 0%-30 %of shrinkage occurs as the tubing cools and returns to its original appearance.
