THE RESIN* THAT TAKES THE HEAT
The ULTEM™ Resin family of amorphous thermoplastic polyetherimide (PEI) resins offers outstanding elevated thermal resistance, high strength and stiffness, and broad chemical resistance. ULTEM is available in transparent and opaque custom colors, as well as glass filled grades.
|
Plus, ULTEM co-polymers are 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 is the result of several years of research and studies - a super flexible and incredibly resistant polymer with an amazing shape memory. ULTEM line includes glasses for men, women and children: perfect for everyday use, comfy and indestructible. |

ULTEM is an incredibly light and flexible polymer which resists to any kind of deformation. Thanks to its durability and lightness it is also used in aircraft and biomedical industry. Thanks to the use of this unique material, breaks have been almost set to zero.
ULTEM will be your adventure companion!
LONG-TERM HEAT RESISTANCE
Excellent stability of physical and mechanical properties at elevated temperatures thanks to high glass transition temperature of 217 °C. Available with relative thermal indices (RTI) up to 180 °C.
STRENGTH AND STIFFNESS
Outstanding strength and amorphous thermoplastic among the available alternatives, with predictable stiffness and strength up to 200 °C. Unfilled, transparent grades are equal in strength to other thermo-plastics with opacifying fillers.
DIMENSIONAL STABILITY
Among the most dimensionally stable thermoplastics available, offering predictability over a wide temperature range. Filled grades offer exceptionally high-tolerance dimensional capabilities.
ENVIRONMENTAL STRESS & CRACKING RESISTANCE
Unlike most other amorphous thermoplastics, ULTEM resins retain strength and resist stress cracking when exposed to automotive and aircraft fluids, aliphatic hydrocarbons, alcohols, acids, and weak aqueous solutions.
FLAMMABILITY, SMOKE GENERATION AND TOXICITY
Inherent flame resistance without additives in most grades - exceptionally difficult to ignite, with a limiting oxygen index (LOI) of 47%, meeting UL94 V0 specifications in sections as thin as 0.41 mm. Generates extremely low smoke as per the NBS smoke evolution test, with products of combustion no more toxic than those of wood.
PROCESSABILITY
Can be extruded, thermoformed, extrusion blow molded and injection molded, and flowability permits long flow lengths down to 0.2mm thick using conventional injection molding equipment.
