CS Unitec has come up with a green alternative for grinding steel — they make the backing plates of their PLANTEX discs from natural hemp fiber with a 1% polypropylene binder.
The hemp backing plate is quieter, it absorbs heat, it maintains its shape but is also flexible, it’s easily disposed of, and it’s a renewable resource. And since it’s self-trimming, you can use it down to the last bit. We applaud this very innovative use of a new technology.
CS Unitec makes the discs in Germany, where industrial hemp cultivation is legal. In the US, you can’t legally grow industrial hemp without a DEA permit, which is nearly impossible to obtain.
PLANTEX Discs come in sizes from 4” to 7” and in 40, 60, 80, or 120 grit. No pricing is listed, but the manufacturer claims they cost no more than a medium-quality conventional flap disc.
