SABIC is launching new LEXAN™ EXL AMHI240F filament. This unique product 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. 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.
“LEXAN EXL AMHI240F filament is an excellent example of how SABIC is delivering on its promise to help our customers lead the additive manufacturing industry into the future by providing the high-performance filament technologies they need to succeed,” said Stephanie Gathman, director, Emerging Applications, SABIC. “By raising the bar with new additive manufacturing products that perform better than currently available materials, we are opening up new possibilities and allowing OEMs to meet the specification requirements of their applications.”
New LEXAN EXL AMHI240F 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, which is higher than that of general-purpose acrylonitrile-butadiene-styrene (ABS) filaments. This makes the new SABIC filament a great 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 broad 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 new product is the first LEXAN EXL-based filament commercially available for use in Stratasys® Fortus® Classic printers, as well as other printers with sufficient temperature capability and an open-format architecture. The material processes at standard Stratasys® print settings for PC. Filament specifications are 79 mm +/- 0.05 mm diameter and 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.
