Acetal (Delrin®)

A strong, stable industrial plastic

ACETAL is a high strength, low friction engineering plastic that has excellent wear properties in both wet and dry environments. ?Good dimensional stability and ease of machining make acetal an outstanding choice for applications requiring complex machining to tight tolerances.

Homopolymer and Copolymer Acetal
Homopolymer Acetal (Delrin®) has superior room temperature strength, stiffness, and toughness. ?Copolymer Acetal has superior performance in continuous high heat and hot water environments. Copolymer acetal also tends to have less porosity than homopolymer Acetal.
Acetal is also available in a number of enhanced bearing and wear grades, Call to check for availability.
