Poly 77-65

Poly 77-65 is a mid-range to firm hardness, 1:1 mix polyurethane mold rubber that can be used for many general mold making purposes but is widely used for cast concrete applications such as manufacturing of concrete pavers and other cast stone elements. It is also useful for making flexible concrete stamping/imprinting tools and texturing skins.
