recomend a plastic?

recomend a plastic?

(OP)
I have a low production cellphone case that needs the right plastic.  I have tried a polyurethane of 72d and it was too bendy and snapped when bent too far.  Basically the plastic is far too weak.  I wanted to know what to do next, should i find a better polyurethane resin or fill the resin i got with fiberglass?  I read on the forum bout cast nylon, but i cannot find any liquid forms of it, is that even an option?  I need something atleast as hard and durable as abs but after hours of searching i can't find a straight answer.

This is for a rtv mold, low production of around one hundred pcs.  

I went to my plastic store and they recomended. Task 9 as the hardest thing they got in poly so i took it.  Its setting now, unfortunately it takes 60 min so its very slow.  I also got glass powder, the guy said that stuff makes the plastic tougher.D
