Delrin®/Acetal

Easy to machine and fabricate, tough to wear out.

Delrin is the crystalline thermoplastic of choice for impact and wear resistance in a wide range of industrial and mechanical applications. With low, consistent internal stress, the material is easily machined and fabricated, experiencing little dimensional change during machining and use. Delrin is also known as acetal.

Delrin also resists moisture – making it an ideal material for use in wet environments. Its exceptional strength, stiffness and dimensional stability bring a high level of durability and resilience to application configurations in the automotive, electronics and food processing industries.
