hi we have 2 nero 4's but are wanting to make runs to give even more room that will be joined onto the cage we already have cubes but couldnt get coroplast today so i found this instead to see if its suitable its called polypropylene plastic want to know how hard will it be to use if i can use it and also only using it for the sides will be putting fleece on the floor section

Provided your piggies don't fit through the grids and you don't need it for the floor, then I don't see why would would need any coroplast at all for the sides. I have an outdoor run made entirely out of cubes and I guess your indoor run could be much the same... apart of course from needing a floor of some kind.
