Urethane Rubber 50 is a versatile, two component liquid castable polyurethane elastomer. It combines high strenght and elongation with excellent chemical resistance to create durable flexible molds or castings. This is a high density, impact resistant, flexible rubber that is perfect for making props, cosplay masks, & body armor. Urethane Rubber will pour directly into prepared silicone molds and urethane molds when using the correct mold release such as Mann Ease Release 200 which can be purchased from our store. All of our liquid products are mechanically poured and sealed with Bloxygen to ensure freshness and long shelf life before shipping to the customer. Bloxygen can also be purchased from our store.
