Plastic Professionals compare Copolymer Acetal and Dupont Delrin Homopolymer in Round rods or sheets and plate
Delving into main reason Delrin is the perfect plastic for turning on a machine lathe. It’s simple to turn, although it requires reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have purchased many items from a plastic shop in Anaheim. Smaller pieces usually ship quickly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, as they have very comparable physical properties. They appear 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 probably our primary material for machining,as it gives an great finish both on manual and CNC Machines. Its got a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics chosen within the auto industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
