    I agree with Booze Daily's comment.
    It looks like UHMW, given the whispy burrs left from the band saw.

    I also think it's UHMW.

    It's hard to tell from the picture, but that blue remembers me Nylon MC901.

    I've only seen color acetal in rods. Never in sheets. I don't think it's Delrin.

    You can buy it here, or blue acetal

    .25" X 24" X 48" Blue FDA Acetal Sheet at ePlastics

    I never have, but I see it when I get other types.

    Well, I wrote to the eBay seller and included that photo of the shreds and drill chaff. Here's what they wrote back:

    HI

    IT IS ACETAL , YOU CAN MAKE ANOTHER TEST LIKE YOU CAN PUT INSIDE OF THE WATER IF IT IS SINK IT MEANS IT IS ACETAL . IF IT IS NOT YOU MIGHT SAY IT IS UHMW OR HDPE . BECAUSE ACETAL DENSTIY IS 1.42GR WHICH IS HEAVIER THEN WATER ON THE OTHER HAND UHMW DENSTIY BETWEEN 0.96 - 0.98GR WHICH IS LIGHTER RHEN WATER .

    THANKS

    Regardless of what it is, I think I'll be using something else. Thanks to all who commented and suggested here.

    Interesting. It's the first time I see it.
