ULTEM • THE SPECIAL RESIN

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.  In addition, ULTEM co-polymers are available where higher heat and chemical treatment is required, as well as when greater elasticity is required. They uniquely balance mechanical properties and fabrication capabilities, offering exceptional flexibility and freedom to designers.

ULTEM™ is the result of several years of research and study, it is a flexible and extremely resistant polymer, with incredible shape memory. The lines include glasses for men, women and children, ideal for everyday use, comfortable and indestructible. ULTEM is an incredibly light and flexible polymer which resists to any kind of deformation. Because of its durability and lightness, it is also used in aircraft and biomedical industry, and breaks have been almost set to zero.



PROPERTIES OF ULTEM

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.
Filled grades offer high-tolerance range properties.

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.


* ULTEM is a PEI product manufactured by the Saudi Co. SABIC, as a result of acquiring the GENERAL ELECTRIC Plastics Division in 2007 for U$11.6 bln.
