- Product Highlight
The ULTEM™ family of amorphous thermoplastic polyetherimide (PEI) resins offer outstanding elevated thermal resistance, high strength and stiffness, and broad chemical resistance. ULTEM™ copolymers are also available for even higher heat, chemical and elasticity needs.
ULTEM™ resins uniquely balance both mechanical properties and processability, offering design engineers exceptional flexibility and freedom. ULTEM™ resins are also inherently flame retardant and possess excellent dielectric character. ULTEM™ resins are therefore an excellent candidate for your electric vehicle battery needs where high heat resistance is required.
With its appreciable flow and dimensional stability, coupled with excellent resistance to Li-ion electrolyte, ULTEM™ resins such as ULTEM™ CRS5011 resin are today being used for insulation of Li-ion cell terminals. Given its excellent dielectric character, ULTEM™ resin is also an ideal candidate for bus bar insulation. For other powertrain elements, such as DC power converters. ULTEM™ UTF120 dielectric film is already enabling high temperature film capacitors.
