PT Flex 85 Liquid Rubber is a two-part, liquid polyurethane system that hardens (RTV) into a yellow / orange Shore A85 rubber. PT Flex series rubbers are specifically designed for prototyping and model building applications and offer fast casting times (approx. 5 minutes) and fast exit times (approx. 2 hours) and a slightly higher viscosity for the PT Flex series of 1600 cP.
The extremely hard Shore A 85 p.u. rubber which is well machinable. By adding the Poly colors or the Pasta, the PT Flex series can easily be colored. When pouring the PT Flex products into an addition silicone mold such as the Eurosil silicone, no release agent needs to be used.
The PT flex series is available in a Shore A 20 to Shore A 85.
