Plastic Professionals compare Dupont Delrin and Acetal Copolymer in Round rods or sheets and plate
Reasons Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s simple to turn, but it does require reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have bought many items from Industrial Plastic. Smaller pieces always ship quickly and everything was well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are exceptionally tough and easily machinable, and they have similar physical properties. They appear the same, but in practical uses there are a few differences that may make one preferable than the other. It also depends heavily on your application. As with any plastic materials, be 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,giving an excellent finish both on manual and CNC Machines. It has a pretty 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, hardness and toughness, giving it superb 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 in addition to its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics chosen within the auto industry because of its long term dimensional stability and durability. It provides 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 will result in components that won’t expand or alter dimensions due to contact with water.
