Flex 50 is a medium-firm urethane rubber designed for casting flexible molds, replicating soft rubber parts, and creating durable prototypes. With a shore hardness of 50A, it provides the perfect balance between strength and flexibility, making it an excellent choice for gaskets, grips, and high-detail molds.
Its low viscosity ensures superior detail reproduction, while vacuum or pressure casting is recommended for bubble-free results.
