Product Description

The opaque black acetal copolymer round rod has a standard tolerance and meets American Society for Testing and Materials ASTM D6778 specifications. Acetal copolymer is a strong, rigid plastic that offers excellent dimensional stability, enhanced by the material's moisture and creep resistance, and maintains its properties better than acetal homopolymer when exposed to hot water, hot air, and humid environments. The material has a low-friction surface and excellent abrasion resistance.

Plastic refers to a group of synthetic or semi-synthetic materials that have been engineered to achieve specific properties. The most notable characteristics of plastics are its low weight, machinability, corrosion resistance, and typically good thermal and electrical insulating properties. Certain plastic grades also offer optical transparency similar to glass, low-friction or self-lubricating surfaces, and exceptional impact resistance. Depending on their properties, certain plastic grades can be used as alternatives to metal, glass, and ceramic. Unlike metal, plastic may experience creep, which is deformation caused by longtime exposure to a constant load.

Tensile strength, used to indicate the material’s overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Impact resistance is the measure of a material’s ability to absorb a shock of energy before breaking.

I bought a chunk of this material to make a reading stylus. I know it isn't recommended to use a stylus for speed reading, but I use one, it seems to act as a sort of 'momentum' to keep me moving. I wanted some kind of plastic that would slide smoothly over the pages and I found it. This material is light weight and exhibits low friction, yet doesn't wear inordinately. It worked easily enough on my wood lathe for the short piece I was turning, but it did tend to bend rather too easily for turning. You have to keep your length/width ratio pretty thick. I went ahead and bought the three foot piece (stylus only five inches) and I'm sure I'll find other useful applications for the remainder. Good stuff. Too the price from this supplier was something unusual, FAIR!

Good price on the acetal (delrin) rod. You can buy delrin (acetal) bushings from various places, but they are pretty expensive. I made my own bushings using a lathe and they are just as good, and a lot less $$$, as any that I could buy.
I made frame end shackle bushings for my Suzuki Samurai, to stabilize the shackles/axle. Before, the axle would shift under the vehicle when I turned the steering wheel and/or was in off-camber places. But after I made the acetal bushings, the axle stays in place and the steering is greatly improved. I also saw no loss of flex in the suspension, after making/installing the acetal bushings.
I also bought a rod of nylatron at the same time, and have made shackle bushings out of it too. I prefer the acetal/delrin, over the nylatron. The acetal seems to be a stronger product, even though I haven't had any issues with the nylatron.

Whatever lenght you order you will get roughly half an inch under it. I guess that's a good way to make their stock last but keep that in mind when you order. I ordered a 24 and 36 inch bar and both were roughly an .5 - .75 short

A few hours in the sun and I could bend it to a 4.5 inch radius, then thread it to 1/4"-20

Used this to turn out AR/M4 take-down tools. Derlin has shown the best material for this project. Cut the rod into short sections & turn on lathe to correct diameter for punching out take down pins & pivot pins. The opposite end, I file to shape like a flat blade screwdriver to be used as a light scraping tool that doesn't mar. I then drill a hole near blade end for attaching to keyring. Machines well at proper speeds. Works well for my applications.

Delrin is a great plastic for turning on a machine lathe. It is easy to turn, but it requires slow speeds. I use this stuff to make Scottish smallpipes chanters. I have purchased numerous items from Small Parts via Amazon. Small Parts always ships promptly and everything has been well packed. I have never had a problem with an order. Best of all Small Parts honors Amazon Prime -- free 2-day shipping.

I bought this to use as a non-marring punch on my AR lower for the takedown pins. I had to shave it ever so slightly because it was a tight fit in the hole at first, but other than that, it does a great job of tapping out my takedown pins without leaving marks on my lower.
