Acetal – also known by its Dupont brand name Delrin ® – is most commonly used in mechanical and electric engineering, as well as medical applications. Other applications include automotive, various household items, and even sports.
While Acetal certainly offers many advantages compared to metal – including low friction, high wear resistance, more stiffness and strength, superior dyeing potential, and good dimensional stability – there are also several marked disadvantages. These include: UV degradation, shrinkage and warping (under certain temperature- and weight-related circumstances), poor reaction to acids and bases – and hot water, flammability, and bonding difficulty.
Because of these drawbacks, Acetal is not used in domestic plumbing and other water supply infrastructure. Be careful to inquire as to whether your plumbing involves any Acetal components, as they may fail after time, causing severe damage in the form of leaks.
