Polypropylene vs PVC perforated sheets

I need to buy a 1/8" thick plastic perforated sheet for a DIY filter. They are available in Polypropylene and PVC. Does anyone know which one would be more rigid, and which one would be easier to cut without cracking using just a heavy duty pair of scissors? Thanks.

I wouldn't try to cut either material in that thickness with scissors. I would instead, just score the material, using a straight edge to guide a utility knife, until I had nearly cut through the material, then break it off. I find that method works for almost any plastic, even acrylic.

The Polypropylene would be a better candidate for scissors than PCV.
For that thickness, scoring will work.
If you need precision, you should use a saw.

Yeah I agree, that's what I would do too.
