PT Flex 20


PT Flex 20 Liquid Rubber has the lowest durometer (Shore A20) in the PT Flex Series. It is a very flexible and fast-curing rubber designed for prototyping and model making applications. It offers a 4-minute pour time and a ~2-hour demold time 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.
