Poly PT Flex 85 Liquid Rubber is the firmest, A~85, yet still slightly flexible, fast-curing rubber, which has been developed specifically for prototyping and model making applications. And is very low in viscosity making it easy to mix and pour without trapping bubbles.
It is excellent for casting decorative objects, production parts, tools, models, patterns, duplicate masters and more. With the addition of Poly Color Dyes, PT Flex products can be used to cast parts of any color.
