Delrin* is a homopolymer acetal. Stocked in rod and plate, it offers slightly higher mechanical properties than Acetron GP Acetal, but may contain a low-density center, especially in larger cross-sections. Delrin is ideal for small diameter, thin-walled bushings that benefit from the additional strength and hardness of homopolymer acetal.
