Osaka-based Japanese diversified materials conglomerate (TSE: 3101). In 2022, spun out its specialty materials businesses into Toyobo MC Corporation (subsidiary), which produces: ZYLON® (PBO fiber — the world's sole commercial producer), IZANAS® (ultra-high-molecular-weight polyethylene fiber), TSUNOOGA® (high-strength polyethylene), HOLLOSEP® (cellulose triacetate hollow fiber membranes for dialysis and water treatment), VYLON® (polyester resins), BREATHAIR® (3D polyester cushioning). ZYLON PBO fiber (decomposition temperature 650°C, LOI 68) is produced at the Iwakuni Production Center in Iwakuni, Yamaguchi Prefecture. Full-scale ZYLON production began 1998. Toyobo MC is simultaneously the world's only PBO fiber producer AND the world's leading hemodialysis membrane maker — two life-critical medical and safety products from one Japanese specialty chemicals company. Toyobo paid $66M in 2018 to resolve False Claims Act allegations related to defective Zylon-containing bulletproof vests sold to US law enforcement (2003-2018 litigation).
