VFI®-3070 70 A Polyurethane Casting Rubber

VFI®-3070 70 A Polyurethane Casting Rubber is a fast setting, injectable or pourable polyurethane rubber that is ideal for making parts and castings. A 1:1 mix ratio gives added usability and a quick gel time allows users to demold parts quickly. VFI- 3070 works well in urethane and metal molds and can produce parts of varying sizes. A high tensile strength and tear strength gives the impact resistance and durability to work for many different high-use parts.

70 A fast setting urethane rubber made for casting parts and is used when a two part 1:1 is necessary for mixing.
