Delrin (generic: acetal) is a low-friction, high-stiffness material. It is used in applications ranging from auto parts to musical instruments. With a relatively high toughness and minimal elongation, Delrin boasts excellent dimensional accuracy.
Fictiv also offers Delrin AF (13% PTFE-Filled) and Glass-Filled Delrin.
When compared with standard Delrin, Delrin AF has an increased coefficient of friction for applications that require lubrication. With an excellent wear resistance, toughness, strength and dimensional stability, this material is often found in load bearing applications such as bushings, bearings, cams, thrust washers, gaskets and valve seats.
Glass-filled Delrin offers superior stiffness and dimensional stability with a high resistance to creep. Glass fibers increase impact resistance and fatigue endurance. This material is commonly used for automotive applications, construction, fixturing, and gear manufacturing.

Warping
Due to the composition of Delrin and temperatures from machining, it is highly susceptible to warping on large, flat parts or where there are thin walls. We recommend avoiding thin walls; if you need thin walls, use fasteners to clamp down your design.
Cost Saving Tip
To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
Can Delrin be machined?
Delrin can be used in cnc machining. It is a good plastic for applications that will experience lots of friction, require tight tolerances, or need a high stiffness material.
Can you laser cut Delrin?
Yes, because Delrin can easily be removed by the laser beam, it is especially useful for laser cutting or engraving.
How do you cut Delrin plastic?
It’s possible to cut Delrin with a bandsaw, RAS, miter saw, or lathe.
Is Delrin stronger than nylon?
Nylon is a strong and durable plastic, applicable to a wide variety of purposes, however it’s not as strong as Delrin.
