Acetal Copolymer - PTFE filled Specifications

Description

PTFE-filled acetal copolymer is an outstanding bearing and wear material for use in both wet and dry environments. PTFE-filled acetal copolymer 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 the material to be used without additional lubricants in applications where grease and oil are undesirable. The white grade of PTFE-filled acetal copolymer is FDA compliant for use in food processing machinery.

Applications

Bearings • Bushings • Slide pads • Gears
