Compare and contrast Copolymer Acetal and Homopolymer Acetal in Sheet and Rods
Homopolymer Acetal or Delrin is the best plastic for turning on a machine lathe. It’s pretty easy 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 a plastic shop in Anaheim. Small pieces always ship promptly 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 durable and easily machinable, as they have comparable physical properties. They appear the same, but in practical uses there are some differences that may make one better than the other. It also depends on your application. As with all plastic materials, make sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,giving an nice finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the ideal 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 outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications 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 excellent 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 provides solutions for designers to help them create long lasting and very durable components. Another popular area for Tecaform AH is in marine applications. This environment suits acetal quite because its low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
