Note:
The large majority of "Delrin AF" shapes commercially available today are actually blended down to a 13% PTFE known as Delrin AF Blend. For this reason, when customers require a full 20% PTFE filler, we ask that they request material as "Full-Strength Delrin 100AF". Full-Strength Delrin 100AF is available as a custom-order only, as no domestic extruders manufacture this grade as standard.
