3D-printable polyurethane material for low-compression set billet, seal and gasket applications
DOWNLOAD CHROMALAST 90 TECHNICAL DATA SHEET >
ChromaLast™ 90 is a strong, flexible polyurethane material with a high degree of crosslinking. It was designed for high-temperature applications requiring high tensile strength, good hydraulic oil resistance, and low compression set. It also has improved hydrolytic stability. It has a temperature range from -20° C to 120° C.

ChromaLast: Made for additive manufacturing
ChromaLast resins are flexible, colored, translucent or opaque polyurethane resins. They have a very low compression set, making them suitable for applications with long-term static or dynamic load. They have been specifically developed for applications with our RX-AM™ platform. This unique system is being evaluated for applications ranging from rail and automotive to oil and gas to seals and gaskets. ChromaLast is available to make near net-shape parts, such as billets, that can be machined into tight tolerance seal applications.
