Poly PT Flex Series liquid rubbers are pourable polyurethane casting rubbers specifically designed for prototyping and model making applications. Unlike liquid polyurethane mold rubbers used primarily for mold making, these castable rubbers are low in viscosity and are fast curing so they can be demolded rapidly. These rubbers are available in the range of Shore A20 to A70 hardness and are excellent for casting decorative objects, production parts, tools, models, patterns and more. With the addition of Poly Color dyes, Poly PT Series rubbers can be used to cast flexible parts of virtually any color.
