Dupont Delrin Sheet - High Quality Machinable Plastic Material
One of the most widely used engineering plastics is acetal sheet, particularly on the West Coast (East Coast favors Nylon Polyamide for some reason). It is a polymer which is created through the polymerization of formaldehyde. This semi-crystalline machinable material was initially used commercially in the 1960s. Due to its many advantages, it has been extensively used commercially in a vast range of applications.
Acetal sheet is quite tough and hard, and it has very good reaction to machining leaving a smooth, consistent end surface. Due to its remarkable quality of very low dampness absorption, it is popularly used in the food manufacturing industry and in other areas where it will most often come into contact with h2o, like in the marine industry. This is because it does not warp or expand when it gets into contact with h2o. It has in fact been authorized by the Food and Drug Administration (FDA) as safe and hygienic for use in food processing equipment. This plastic is also used in the engine vehicle manufacture industry due to its toughness and dimensional stability. With it, designers are able to create long long lasting and durable components.
Dupont Homopolymer Sheet compared to Acetal Sheet
Key features of Acetal (Acetal Homopolymer) sheet include high power, very good opposition to wear and abrasion, very good dimensional stability, excellent slipping attributes and electrical insulation. Among its attributes include a melting temperature of 165oC, a 100oC maximum long-term temperature and a 130oC maximum short-term temperature. This makes it ideal for use with automated contemporary high speed CNC machines creating high quality finished products.
Due to its stability, acetal sheet is used to replace other metallic and steel components in engineering. It remains accurate for a long time creating good dimensional stability. That is why it is very popular in the marine industry as many other materials are unable to perform well in numerous marine applications as acetal sheet does.
Acetal or Delrin sheets are normally available in various dimensions for person needs. But it is popularly available in 24 inches X 48 inched and 48" X 120" sheet sizes. It also comes in thickness which range between .030 inch and over an amazing 6.0 inches thick. This plastic can be cut quite well using standard cutting instruments, the most common would be CNC machining.
Both Delrin and Acetal Sheets have excellent physical properties
This engineering plastic also comes in two popular grades. The most common grade is the co-polymer grade which is also most popular. This is because of its relatively better chemical opposition which makes it ideal for use in food manufacturing industries.
The other grade is the homopolymer, this is the Dupont Delrin resin, whose thermal expansion is lower. It is stiff and hard which makes it ideal for use in specific areas. This grade is a bit more expensive and has limited size availability range. The other issue with the Dupont Homopolymer is the center-line porosity, or "soft centers" some times found in these sheets and rods.
Apart from the applications already mentioned, Delrin - Acetal sheet can be used in very many other areas. For example it can be used on bearing pads. This is because of its very low friction coefficient, or high slip surface. In slide ways drag, this might be a disadvantage. At the same time, long term service would be expected. When using this type of plastic, the cost versus value ratio is very high. The exceptional value in use is dramatically higher than the relativley low cost.
It can also be used for jigs and fixtures. This is because it is quite steady and does not absorb a lot of dampness. This would make jigs that are made using acetal sheet to be steady and helpful for a long period of time.
With so many helpful attributes, Delrin - Acetal sheet remains one of the most popular engineering plastics of all occasions.
