With exceptional strength, heat resistance, durability, and light weight, Leona™ nylon 66 filament is widely used in industrial applications, notably airbags and tire cord for the automotive industry, satisfying rigorous quality requirements. Under the Cs for Tomorrow 2018 medium-term management initiative, Asahi Kasei has identified automotive markets as a focus for expansion in the Material sector, which includes fibers and textiles operations. Leona™ nylon 66 filament is enjoying remarkable growth in its predominant application of airbags, as vehicle production in Asia increases and the airbag installation rate rises in line with heightened safety requirements. This capacity expansion will enable Asahi Kasei to meet increasing demand as the market continues to grow.
