Product Description
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.

Data provided by Quadrant Engineering Plastic Products from tests on stock shapes and parts produced by Quadrant EPP.
