What Sekisui does

SEKISUI America Corporation (SAC) is the North American regional headquarters of Japan's SEKISUI Chemical Co., Ltd., a $12 billion (2017) global chemical and manufacturing group founded in 1947. SAC itself was established in 1983 in Secaucus, New Jersey, to coordinate a growing number of North American operating companies. It is organized as a holding structure for ten wholly-owned subsidiary companies that serve industrial B2B markets across aerospace, medical diagnostics, automotive, architectural construction, infrastructure, and specialty chemicals. The company employs 1,001–5,000 people and maintains 24 production and office locations across the USA, Canada, and Mexico, with SEKISUI Plastics Corporation having been the first Japanese manufacturer to open a US plant in 1963.

SAC's operating subsidiaries each maintain distinct product lines and go-to-market models. SEKISUI Aerospace (acquired 2019 from AIM Aerospace) supplies advanced thermoplastic composite structures, systems, and engine components to global aerospace OEMs through long-cycle enterprise sales. SEKISUI Diagnostics, formed in 2011, supplies clinical chemistry, coagulation, immunoassay, rapid test, and point-of-care diagnostics systems and reagents to physicians and laboratories globally. SEKISUI KYDEX, acquired in 1990, produces proprietary thermoplastic sheets using an Infused Imaging™ technology and a Quick Response Manufacturing (QRM) model for bespoke short-lead-time materials. SEKISUI S-Lec (America and Mexico) manufactures PVB interlayer films for automotive and architectural laminated glass. SEKISUI Voltek (operating since 1969) is the leading producer of cross-linked closed-cell polyolefin foams used in healthcare, automotive, packaging, and industrial applications. SEKISUI Specialty Chemicals America (2009) supplies polyvinyl alcohol polymers and copolymers (Selvol, Advasol) along with CPVC and other specialty resins. SEKISUI SPR Americas (2005) provides trenchless spiral-wound pipeline rehabilitation services to municipalities and utilities across North America. SEKISUI Products imports high-performance pressure-sensitive adhesives and foam tapes, and SEKISUI POLYMATECH focuses on materials for the electronics field.

SEKISUI America generates revenue primarily through direct B2B enterprise sales of manufactured hardware (chemicals, films, foams, thermoplastic sheets, composite structures, diagnostic instruments and reagents) and service revenue from the SEKISUI SPR Americas trenchless rehabilitation business. The model is quote-based and project-based, typical of industrial B2B manufacturing, with the QRM model enabling bespoke low-volume runs at KYDEX. Distribution is direct, with 24 locations supporting local manufacturing and customer engagement. The company maintains an active Kaizen continuous-improvement program that has produced $2.4M (2019) and $4.0M (2018) in documented annual savings and cost avoidance, and the parent has been recognized eight times — including six consecutive years as of 2023 — on Corporate Knights' Global 100 Most Sustainable Corporations list, anchoring its sustainability and ESG positioning for global enterprise and government customers.
