Looking for Shore 100 TPU

[peterbrown77 0]

Hi -

 

Made some parts out of Hatchbox TPU, Shore 95A. They could be a little harder but I'm having trouble locating Shore 100 TPU - does anyone know a source?

TIA

Hi, where are you located? There are lots of TPU 98A filaments out there, and some even harder TPU 58-60D ones. Shore 100A isn't reliably measureable, since it is defined as zero indentation by the probe - a granite slab would also have "Shore 100A", even if this rating is meaningless. Shore D uses a different probe and a much higher loading. See also http://www.m-coat.com/Shore A-D conversion.pdf .

Thanks for the reply - I'm in CT.

 

I found some 70D on Amazon, let's hope it's not a typo hahaha.

Ok, so you're in the U.S. - meaning it probably won't help you if I give you a link to some european shop's offer ;)

 

Glad that you found something - be aware though that Shore 70D will be really, really hard, not just a little bit harder than Shore 95A. With 70D, you are well into the "territory" of normal thermoplastics, for example PP will, according to the sources I found online, have between 70 and 80 Shore D. With TPU, you will still get the elastomeric spring-back properties PP doesn't have, but a Shore 70D TPU won't be very flexible anymore probably.
