Comparing Copolymer Acetal and Homopolymer Acetal in Sheet and Rods

Delrin is a great plastic for turning on a machine lathe. It is very easy to turn, however it does require slower speeds. I use this stuff to make Scottish small pipes chanters. I have ordered many items from Industrial Plastic. Small parts always ship promptly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are incredibly tough and easily machinable, and they have comparable physical properties. They do appear similar, but in practical use there are some 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 desired properties you may need for your application.
Our Acetal Sheet is probably our best material for machining,as it gives an nice 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 uses and is particularly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval and its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics chosen within the automotive industry because of its long lasting dimensional stability and durability. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Tecaform AH is in water applications. This environment suits acetal well because its low moisture absorption results in components that will not expand or change dimensions due to contact with water.
