Both materials are in the Polyolefin family of plastics, along with Polypropylene (PolyPro) and UHMW (Ultra High Molecular Weight). Manufactured by a variety of manufacturers under the names: Polyboard®, Polymar®, Hostalen®, Polystone®, Hitec®, Sanatec®, Sanalite®, Ultra Ethylux®, Polycarve®, and Densetec®.
For great abrasion resistance, very low density and FDA/NSF compliance, Polyethylene is an excellent choice.
Occasionally we are asked for the difference between Acetal and HDPE – here is an explanation.

“Thank you for suggesting Polyethylene plastics for our cutting surface. Works great. Took home a few of our remnants, and my wife loves them for cutting in the kitchen” – Eddie T.
“We have been using your LDPE for our metal bending press, and it works great. This prevents the press from scratching or denting the metal as we been it. Thanks for the help” – Robert P.

We are looking to get some HDPE stock, 20 inch diameter x 42 inch length or half of those two dimensions for a machined prototype for our senior projects class. If you could send me a quote on those two pieces, and have any recommendations of other plastic polymers that would be good to machine and make a displayable model of our design. We are looking to keep it low cost as possible and will be only for visual aid as long as the material can be machined easily and consistently.
Stefan, We can certainly supply 20″ diameter rod. However, you mention that you are looking for a low cost option. Any plastic material that is 20″ in diameter is not a low cost option, HDPE is one of the least expensive materials, and in 20″ diameter the price is currently about $1,200.00 per foot. All very large diameter plastic rod is going to be in this price range, as it may take several days just to make one length (it is a very slow process).
Can you tell us what you are working on, and the minimum dimensions, perhaps we can find a different way to make it.
Thanks for your interest.

Hi, I’m looking for two solid blocks about 3″x6″x~8″ in the cheapest rigid plastic possible. I will be machining them and then welding them together to make a first-cut prototype. Durability etc. is not a concern at this point as long as they can be welded together with epoxy etc. and are not water soluable.
Would it make more sense to laminate 6 – 1″ thick sheets, cut them to size and then machine in this circumstance?
Thanks,
Greg
Hi Greg, we would recommend using two 3″ pieces of ABS or PVC instead gluing six 1″ pieces. A factor you have to take into consideration is whether or not the glue will dry evenly on the multiple pieces. Simply put, it is much easier for the glue to bond evenly on two pieces instead of six–which will result in an easier product to machine.
