Download Product Brochure (41kb - pdf)
|
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. The white grade of Dielux is FDA compliant for use in food processing
machinery.
The following physical property information is based on typical values of the base PTFE filled
acetal copolymer resin.
