Filament selection assistance please

Filament

I need to make some rubber parts that will be used as a clamping grip. So I’m looking for something with a high friction coefficient.
Ultimately I need to make a damage free clamp that can grip a fiberglass tube with several hundred pounds of force…

I have some NijaFlex, but it’s soft, but very low grip. Before I go buy and test a roll of every filament on the planet - any suggestions?

Thanks

SemiFlex is a bit harder than NinjaFlex, but I don’t believe that it has a better coefficient of friction. In fact, I think that it has a lower coefficient. You might be better off to use your printer to create a mold and use that to form silicone.
