2-part resin more flexible than the Alumilite ?

Posted by pogo on June 24, 2008, 12:42 am

I'm looking for some kind of 2-part resin that is a little more flexible than
the Alumilite product --- something *like* some real
tough nylon plastic.

Any suggestions ?
Thanks!

--Try Tap Plastics; they're a chain of stores on the Left Coast.
You might be able to find what you're looking for there; they've got a good
selection of molding resins and similar stuff.

You can get castable polyurethane resins in very high hardness,
like rollerblade wheels for example. Just make sure you get a
high-strength resin, not a mold-making resin, and take care to
ensure that it's low viscosity before cure. You'll need a vacuum
chamber to de-air during casting.

More resins are available if you can handle a UV or thermo cure
instead of RTV (room temp) - these are more common in commercial
apps.

Thanks! Rollerblade wheels are about the right hardness I need ... any idea what
shore rating that is (ballpark estimate) ?
Thanks again!
