UBE EXSYMO

What UBE EXSYMO does

UBE EXSYMO CO., LTD. (宇部エクシモ株式会社, brand abbreviation UEXC) is a Japanese functional materials manufacturer founded in February 1966 as a joint venture between UBE Corporation and Nitto Boseki Co., Ltd. The company became a wholly-owned subsidiary of UBE Corporation in October 2003 and operates from headquarters in Tokyo with manufacturing facilities in Gifu and Fukushima, a Specialty Products Research Laboratory in Gifu, regional sales offices across Japan, and a 100%-owned manufacturing subsidiary in Wuxi, China established in April 2002. As of March 31, 2025, the company reported 357 employees on its English corporate page.

UBE EXSYMO develops and manufactures specialty functional materials organized around five proprietary core technologies: extrusion molding (TWINCONE hollow boards, SINGLE CONE), spinning and drawing using high-pressure steam (SIMTEX high-strength polypropylene fibers at 2x strength and 3x elastic modulus of conventional PP; AIRYMO ultra-fine polyolefin fibers down to 0.2 dtex), pultrusion (COMPOSE FRP pipes and DANPOLE tunnel supports), sol-gel synthesis (HIPRESICA monodisperse silica particles for LCD gap spacers and semiconductor sealing, with particle sizes from 0.2μm to 70μm), and reel-to-reel lamination (UPISEL and EXSYLAM flexible copper-clad laminates for high-frequency and heat-radiation applications). The portfolio is sold under 20+ registered Japanese trademarks.

The company operates a B2B enterprise sales model with five dedicated sales departments (Industrial Products, Electronic Materials, Performance Plastics, Fiber, Industrial Materials) and direct sales offices in Tokyo, Osaka, Nagoya, and Fukuoka, serving customers in the electronics, automotive, agriculture/fisheries, infrastructure/environment, and hygiene/daily-life industries. Pricing is quote-based with no public disclosure; long-selling lines such as DANPOLE have shipped 3.5 million+ units and COMPOSE holds dominant share in Japanese seaweed aquaculture support poles. Revenue is not publicly disclosed. Revenue streams are primarily hardware sales of plastic products, synthetic fibers, composite materials, fine ceramics, and electronic materials, with the parent UBE Corporation providing group-level distribution, technology licensing (UPISEL/UPILEXR polyimide trademarks), and strategic alignment.
