PTFE Filled Acetal is manufactured from Delrin® homopolymer resin which has been uniformly filled with a dispersion of 13% PTFE fiber filled homopolymer acetal. The benefits of PTFE Filled Acetal are improved wear characteristics along with strength, toughness, dimensional stability and machinability.
PTFE Filled Acetal is a unique thermoplastic material for use in moving parts in which low friction and long wear life are important. It retains 90% of the mechanical strength of unfilled acetal homopolymer, while offering very low friction and almost no "slip-stick" behavior.
