PT Flex 60 Casting Rubber – New & Improved

PT Flex 60 Liquid Rubber is a mid-range hardness (Shore A60), fast-curing polyurethane rubber in the PT Flex Series.

It offers a 4-minute pour time and a ~2-hour demold at room temperature (30-minute demold time at 70°C) and is very low in viscosity which makes it easy to mix and pour without trapping bubbles.

PT Flex Series rubbers are designed for prototyping and model making applications and are excellent for casting decorative objects, production parts, tools, patterns, duplicate masters, props and more. With the addition of PolyColor Dyes, PT Flex products can be used to cast parts of any color.
