Product description

PTFE-bars
According to the various manufacturing methods, the following distinctions are made:

Extruded bars (ram extrusion)

Ram extrusion is a continuous press-sintering procedure. PTFE powder is processed to semifinished products by applying it via a dosing mechanism to metal tools (bars, tubes, profiles) heated to sintering temperature.

Bars of a diameter from 4.0 mm to 160 mm are extruded in lengths up to 3000 mm.
Dimensions according to dimensions list 1100
(Overlengths available on special order)

For lower diameter tolerances, extruded bars up to 60 mm in diameter can also be ground.
Dimensions according to dimensions list 1110

Pressed bars (press processing)

PTFE powder is compressed in metal forms to simple geometrical forms using hydraulic presses and then sintered in hot-air ovens (in special cases in an N2 atmosphere). The sintering cycle is dependent on the size and dimensions of the formed parts; it involves controlled heating, controlled maintenance of temperature and controlled cooling.

Bars of a diameter from 30 mm to 775 mm are pressed in lengths up to 300 mm.
Dimensions according to dimensions list 1200

PTFE-tubes
As in the case of bars, a distinction is made between extruded tubes (ram extrusion) and pressed tubes (press processing):

Extruded tubes (ram extrusion)

Tubes of a diameter from 10 mm to 205 mm are extruded in lengths up to 3000 mm.
Dimensions according to dimensions list 2100

Pressed tubes and rings (press processing)

Tubes of a diameter from 35 to 390 mm are pressed in lengths up to 300 mm.
Dimensions according to dimensions list 2200

Rings of a diameter from 405 to 1440 mm are pressed in heights up to 100 mm.
