SABIC, a global leader in the chemical industry, launched LEXAN EXL AMHI240F filament, a polycarbonate (PC) copolymer that delivers high impact performance and low-temperature ductility.

The filament addresses the need for higher-performing materials in the industrial sector, and is for use in Stratasys Fortus Classic industrial printers. It is a potential material of choice for aerospace, consumer electronics and automotive applications.

LEXAN EXL AMHI240F filament is the first of several new materials with distinctive performance characteristics that the company plans to launch in the coming year.

New filament features a high level of toughness, and improved ductility at room temperature and at temperatures to -30 °C. Compared to standard PC, this material delivers up to four times better notched Izod impact at room temperature, and up to three times better at -30 °C, depending on print orientation.

LEXAN EXL filament has a heat deflection temperature of 140 °C, which is higher than that of general-purpose acrylonitrile-butadiene-styrene (ABS) filaments. This makes the filament a candidate for use in applications that operate at elevated temperatures.

LEXAN EXL AMHI240F filament complies with Underwriters Laboratories’ UL94 V-0 flammability standard at 3.0 mm in flat (XY) and on-edge (XZ) orientations, making it appropriate for a range of applications requiring fire resistance. It is available globally for sampling. It is initially offered in black, with plans to launch additional colors, including white, in the near future.

Filament specifications are:

• 1.79 mm +/- 0.05 mm diameter
• 1510 cc / spool

In 2018, SABIC plans to launch several more differentiated products based on its high-performance materials portfolio, including filaments based on ULTEM polyetherimide (PEI) and EXTEM thermoplastic polyimide (TPI) resins. The new filaments are designed for applications that require higher temperature performance.
