Delrin®, a homopolymer acetal, is also manufactured and stocked in rod and sheet. Delrin® offers slightly higher mechanical properties than Acetron® GP Acetal, but may contain a low-density center, especially in larger cross-sections. Copolymer acetal also offers better chemical resistance than homopolymer acetal. Delrin® is ideal for small diameter, thin-walled bushings that benefit from the additional strength and rigidity of homopolymer acetal.
Delrin® AF Blend
Delrin® AF Blend is a unique thermoplastic material for use in moving parts in which low friction and long wear life are important. Delrin® AF Blend is a combination of PTFE fibers uniformly dispersed in Delrin® acetal resin. This combination offers better wear characteristics than unfilled Delrin®.
Delrin® AF 100
Unblended Delrin® AF offers a slightly higher limiting PV and lower coefficient of friction due to additional PTFE content. This added PTFE typically decreases the wear capability and impact strength. Delrin® AF 100 is available on a custom basis.
