Is Polycarbonate the Best Material for Durable CD Cases?

[LockyPhysics]

Polycarbonate fracture toughness?

I am doing a project in which I have to make a cd case out of a material which is transparent, has a young's modulus not too different to polystyrene, can't cost more than twice polystyrene and has a fracture toughness better than polystyrene!

Polycarbonate looks good so far but I can't find the fracture toughness of it anywhere.

Please Help...
It's due tomorrow!

Thanks!

Polycarbonate is highly resistant to fracture, which is why I always recommended it for kids' lenses. You can find shatter-resistance information if you look around.
