Hello -- we are trying to purchase a blade that is: 1) safer for our employees (in terms of cuts) and 2) longer-wearing than PTFE. We are thinking of trying a carbon-impregnated PTFE, which makes the material stronger and anti-static. PTFE is generally considered food-safe, but with this additive, I am not sure. The manufacturer is not providing any kind of food contact guarantees (they like to leave that up to the users!).
Have any of you had experience with this or similar materials?
