Delrin® (Acetal Homopolymer)

Delrin®, a homopolymer acetal.  It offers slightly higher mechanical properties than Acetal copolymer, 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.

AccroSeal® offers both homopolymer and copolymer grades of acetal including enhanced bearing grade materials. We also can provide an acetal that is porosity-free and offered as our standard general purpose grade.

For improved frictional properties PTFE-enhanced Delrin® AF products are available.
