Chart Converting all the Hardness Scales
There are several scales for measuring rubber hardness. Here is a comparison:
https://www.apstpe.com/media/pdf/Shore-Hardness-Scales.pdf
3D Printing Filaments
- Shore A hardnes of 90-95 - [1]. Strain to failure [2] of 400%.
- Ninjaflex 85A [3] and 660% elongation at break
- Softest on the market - Shore 60A [4]
Metrics
- 80-100 Shore A is hard, like shoe soles or shopping cart wheels [5]
- More scales for comparing different objects [6]
Uses
PVC
TPE vs TPU

Hi Mid Continent Plastics,
I'm looking for about 1200 lb of TPU regrind, any color, in the Shore A 70-90 range with good elongation and abrasion resistance. This is for 3D printing of rubber tracks for heavy machinery. Do you have something in stock for this purpose? Thanks,Marcin
