ESS-TOOL® 250 is a new, intermediate epoxy syntactic tooling board designed for use in aerospace, automotive and marine sectors. With enhanced properties for toughness and durability, ESS-TOOL 250 board is designed for use at temperatures up to 250°F (121°C). The material is designed with a small cell structure and formulated with a polymer system that enhances toughness while maintaining temperature resistance, exceptional machinability and superb surface qualities. ESS-TOOL 250 also allows for easier sealing when prepping the tool. Users can produce models and tools with great precision and dimensional stability.
