Naturally white in color it does accept opaque colors well and can be polished to a shine. Delrin is typically difficult to bond but can be bonded with epoxies, polyurethanes and cyanoacrylates (superglue). It has good chemical resistance but is sensitive to mineral acids, chlorine, and alkaline degradation. Common uses include; pump parts, valve bodies, and bearings.
