Compare and contrast Acetal Copolymer and Dupont Delrin in Sheet or Plate and Round Rod
Delrin is the best plastic for turning on a machine lathe. It is very easy to turn, but it does require slow speeds. I’ve used this material to make Scottish small pipes chanters. I have purchased countless items from iPlastic. The smaller parts usually ship quickly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, as they have comparable physical properties. They do appear the same, but for practical use there are a few differences that can make one preferable than the other. It also depends heavily on your application. As with any plastic materials, make sure to check the typical properties data sheet for the appropriate properties you may need for your application.
Our Acetal Sheet is probably our best material for machining,as it gives 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 the perfect combination of high mechanical strength, durability and strength, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is certainly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used 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 Acetal is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
