How to compare Copolymer Acetal and Homopolymer Acetal in Sheet and Rods

Delrin is a great plastic for turning on a machine lathe. It’s very easy to turn, although it requires reduced speeds. I have used this plastic to make Scottish small pipes chanters. I have ordered countless items from a plastic shop in Anaheim. The small parts usually ship promptly and everything has been well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, and they have very comparable physical properties. They appear similar, but in practical use 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 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 usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly 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 help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics used within the automotive industry because of its long term dimensional stability and toughness. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in water applications. This environment suits acetal quite because the low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
