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 thermoplastics 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 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.

Application field

  Since PEI has excellent comprehensive and balanced performance, it has been applied to the parts of electronics, motor and aviation as metal substitute materials for traditional products and cultural life supplies. PEI can be used instead of metal to make optical fiber connector, It can optimize the structure of the component, simplify its manufacturing and assembly steps, and maintain a more precise size. In automobile industry, such as high temperature fittings for manufacturing, the high power lamp and light, control the car cabin outside temperature sensor (air conditioning temperature sensor) and the control of air and fuel mixture temperature sensor (effective combustion temperature sensor). It also can be used for high temperature erosion of lubricating oil vacuum pump impeller, distilling apparatus that operate at 180 ℃ of ground glass joints (following), the lighting of anti fog light reflector.
