Ultem
ULTEM is known for its high thermal performance and strength-to-weight ratio. Used by many in the transportation industry, ULTEM prototypes can be made for fully functional parts or as functional prototypes in heat sensitive applications. This flame retardant, high performance thermoplastic can meet the demands of your heat resistant application and perform well as a functional prototype or final part saving you thousands of dollars when compared to the costs of traditional tooling.
