Product Description
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.
