SABIC, a global leader in the chemical industry, is launching LEXAN EXL AMHI240F filament. This new material is based on SABIC’s LEXAN EXL polycarbonate (PC) copolymer technology, which delivers high impact performance and low-temperature ductility.
The new filament addresses the need for higher-performing materials in the industrial sector, and is designed for use in Stratasys Fortus Classic industrial printers. It suits applications in 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. The filament features a high level of toughness, as well as improved ductility at room temperature and at temperatures down 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.
The 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.
The material processes at standard Stratasys print settings for PC. Filament specifications are:
79 mm +/- 0.05 mm diameter
1510 cc / spool
The LEXAN EXL AMHI240F filament supplements the portfolio of six filament products for Stratasys Fortus Classic printers that SABIC launched in May 2017.
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.
