What 旭・デュポン フラッシュスパン プロダクツ（株） does

DuPont-Asahi Flash Spun Products Co., Ltd. (旭・デュポン フラッシュスパン プロダクツ株式会社) is a Tokyo-based 50/50 joint venture between Asahi Kasei Corporation and DuPont Japan Co., Ltd., incorporated on March 22, 1995 with 450 million yen in registered capital and 43 employees as of June 1, 2026. The company is the exclusive Japanese importer, distributor, and application developer for DuPont™ Tyvek®, a flash-spun high-density polyethylene (HDPE) nonwoven fabric invented by DuPont in 1955, in which 0.5–10 micron continuous ultra-fine polyethylene fibers are bonded solely by heat and pressure to combine water resistance, dust-barrier performance, moisture-vapor breathability, tear strength, and lightweight characteristics.

The portfolio is organized around seven product families: construction building materials (Tyvek® Housewrap, Silver, Drainwrap, Roofliner, Housewrap Tape, Flashing Sheet, Stretch Guard®, and VCL Smart® variable-permeability vapor barrier), medical sterilization packaging (Tyvek® 1073B, 1059B, and 2FS grades compliant with ISO 11607 and JIS T0841), chemical and particulate protective apparel (Tyvek® Softwear®, Tychem® series including 2000 C / 6000 F / 6000 AL / 10000, Proshield® 10/6 SFR, IsoClean®, Chemo Therapy Gown), graphics and printing media, agricultural environmental control materials, industrial active packaging (desiccants and oxygen-absorber pouches), and specialty applications such as a patented New Car Paint Protection System and electronics-component transport wraps. The construction segment — breathable waterproof housewrap, radiant-barrier reflective sheeting, drainage-enhanced wrap, and roof underlayment — is the primary revenue anchor and has been specified in 4M+ Japanese homes since Tyvek®'s 1983 introduction to Japan. Industry-first certifications include a 20-year waterproofing warranty (2013), Better Living general certification for Tyvek® Silver (2015), JIS A6111:2016 Class III 50-year equivalent durability, and ISCC PLUS certification for medical packaging applications (September 12, 2025).

The company operates a sales-led, channel-driven go-to-market: construction products flow through nationwide building-material distributors and the Tyvek® User Support Club; PPE goes through industrial-safety equipment distributors such as Azearth Corporation; medical packaging is sold only as Tyvek® base material to converter partners who fabricate finished pouches and trays. Direct customer engagement is supported via the company website (tyvek.co.jp), downloadable technical catalogs, the Tyvek® Master installer qualification program, the SafeSPEC™ chemical-protection selector tool, YouTube demonstration channels, and small-group ISO 11607/JIS T0841 medical packaging seminars. Pricing is quote-based with no public list, and the stated revenue model combines one-time product sales of Tyvek® materials and converted products with application-development and technical services for new uses. The company's products hold industry-first positions in several Japanese specification niches (radiant-barrier breathable waterproof sheet, 20-year housewrap warranty, JIS A6111 Class III durability, ~80% US market share in sterile medical packaging carried over through the DuPont relationship), and its principal customers are Japanese residential builders and contractors (Hiroshima Kensetsu, Sumitomo Realty & Development, Furugi Ringyo, Fuso Building Materials Industry, Sato Juken, Chiba Kensou), medical-device manufacturers, pharmaceutical companies, industrial workers, and agricultural operators.
