Hot Pour Vinyl

Poly Vinyl Chloride (PVC). Same stuff as Creepy Crawlers or artificial fish bait. Also known as hot pour. Melt in a double-boiler and pour into heat resistant mold. Metal or silicone molds work great.

Polyurethane Foam

Polyurethane Resin

Odorless Casting Resin or Plastic Casting Resin. Not completely odorless but is called that anyway. Mix two equal parts of Part A and Part B and compound will form a solid plastic in a few minutes. Great for artists who want to reproduce their own "Resin Kits." Works great in a silicone mold. Color is sort of a amberish, translucent white. Can be painted, but don't use a silicone mold release.

Quick Wood Prop Putty

Epoxy based resin that works like a combination of five-minute epoxy and plastic wood. Great for making small items, props and repairing holes.

Yellow Net

Open weave netting that works great as a reinforcement for plaster mold casting. 48" wide. Price per linear yard (.91 meter). Excellent replacement for hemp.

General Purpose Silicone Mold Kits
Comes with Rhodorsil Silicone compound and catalyst. Thixotropic additive makes the compound thick so that it can be formed over a vertical surface. Working time about 45 mins. Cures overnight.
