Why Dupont Delrin Homopolymer is the best plastic for turning on a CNC lathe lathe. It really is simple to turn, however it requires slow speeds. I have occasionally used this plastic to make Scottish small pipes chanters. I have purchased countless items from Industrial Plastic. The smaller pieces always ship promptly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are exceptionally durable and easily machinable, and they have comparable physical properties. They do 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, 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 primary material for machining,as it gives an nice finish both on manual and CNC Machines. It has a very low moisture absorption making it the ideal grade for food contact and where the dimensional stability is important. 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 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 engineering plastics used within the automotive industry because of its long term dimensional stability and toughness. 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 alter dimensions due to contact with water.
