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.
Glass Filled and Enhanced Grade Acetal(POM)
Acetal is available in glass-filled grades that offer enhanced strength and stiffness. Acetal is also available in a number of enhanced bearing and wear grades including Delrin® AF, Delrin® AF blend, and TECAFORM™ HPV 13.
