DIELUX®
Dielux
PTFE filled acetal copolymer is an outstanding bearing and wear material
for use in both wet and dry environments. Dielux is frequently used in
place of traditional metal and plastic bearing materials when low friction,
excellent wear properties, and good dimensional stability are required.
The PTFE filler allows Dielux to be used without additional lubricants
in applications where grease and oil are undesirable.
Dielux is available in very large sheet sizes for large parts, strips, and excellent yields.
Applications
- Bearings
- Bushings
- Slide pads
- Gears
Advantages of Dielux
