Mask Making Material Help

I have a digital sculpture of a overhead mask that I plan to 3D-Print in PLA as a master copy once I get passed all the layer line filling and sanding, and I figured the mold should be comprised of a silicone jacket mold and a resin mother mold, which leaves me with one question: "what material will I cast my mask?" I did consider urethane rubber as a casting medium because I wanted the mask to have properties similar to what a latex rubber mask would have: flex and stretch, but I worry about how much flex that could tear the mask in stress points in urethane, and I didn't want my mask to be made of latex because of the mold it would need that could be a problem just to try to release it from Ultra Cal 30 and because of consideration to latex rot deterioration. I am still considering Urethane rubber, but I need some advice from a pro before I even start making the mold. Any suggestions?

    You can cast latex in a silicone mold, brush it in one layer at a time, and allow it to dry before adding the next layer.  "Creature Cast" neoprene rubber is another option for masks.
