Looking at comparisons between Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods
Why Dupont Delrin 150SA is a great plastic for turning on a CNC lathe lathe. It’s simple to turn, however it does require slow speeds. I have used this material to make Scottish small pipes chanters. I have ordered many items from iPlastic. Smaller parts usually ship promptly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, as they have very comparable physical properties. They do look similar, but in practical uses there are some differences that may make one preferable than the other. It also depends on your application. As with any plastic materials, make sure to check the typical properties data sheet for the desired properties you may need for your application.
Our Acetal Sheet is definitely our choice material for machining,as it gives an nice finish both on manual and CNC Machines. It has a very low moisture absorption making it the usual grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is especially valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the automotive industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal well because the low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
