Who makes it

Supplier companies

4 companies produce mdi (pmdi) binder resin for osb.

Wanhua Chemical Group

HQ CN35% share

Chinese specialty chemicals company (SZSE/SSE: 600309, HQ Yantai, Shandong; ~RMB 170B revenue); world's largest MDI (methylene diphenyl diisocyanate) producer — having surpassed Bayer/Covestro and BASF through aggressive capacity expansion over 20 years. Wanhua was founded in 1978 as Yantai synthetic resins factory (a state enterprise) and has grown through acquiring foreign technology licenses and building proprietary MDI production technology. Wanhua's MDI market share has grown from <5% in 2010 to approximately 35-40% of global MDI capacity by 2024. Wanhua was founded on the principle of 'import substitution' of foreign MDI — in the 1980s-90s, China had to import all MDI from BASF, Bayer, and Dow; today China (Wanhua + others) produces more MDI than it imports. Wanhua's competitive strategy mirrors CATL's in batteries and BYD's in EVs: take a technically complex chemical from Western producers, learn the technology (through licensing and reverse engineering), undercut on price, and become the global leader. Wanhua also produces TDI, propylene oxide, and specialty chemicals from its Yantai and Ningbo complexes.

BASF SE (Battery Materials / Catalysts)

HQ DE18% share

German chemical company (XETRA: BAS, HQ Ludwigshafen; ~€69B revenue); Battery Materials division produces NMC cathode active material at Schwarzheide, Brandenburg (former East Germany; site of a Nazi-era synthetic oil refinery, now a major BASF specialty chemicals site). BASF's Schwarzheide plant produces NMC622, NMC811, and high-voltage NMC cathode active materials for European and Korean battery manufacturers. BASF is the largest European-headquartered CAM producer. BASF also holds a stake in Norilsk Nickel (Nornickel) — Russia's largest mining company — through its Catalysts division which uses Nornickel palladium and rhodium in automotive catalysts: the same BASF that makes NMC cathode material also sources precious metal catalysts from the Russian company whose nickel and cobalt feed into battery supply chains. BASF Battery Materials won a production contract with BMW for its Neue Klasse EV battery cathode — one of the most important European CAM contracts of the 2020s.

Covestro AG(COV)

HQ DE18% share

German specialty polymer and coating company (XETRA: 1COV), spun out of Bayer AG in 2015. Became the dominant global fiber optic coating supplier when it acquired DSM's Resins & Functional Materials business for €1.61B (announced Sep 2020, closed April 1, 2021) — absorbing DSM's 40-year legacy in optical fiber coatings. Then acquired JSR Corporation's 30% stake in Japan Fine Coatings Co., Ltd. (Tsukuba) in January 2022, becoming sole owner. Now self-states it "produces more than 50% of the world's optical fiber coatings." Brands: DeSolite® (primary/secondary UV-cure acrylate coatings), Cablelite® (ribbon matrix/inks), Bufferlite® (tight buffer). Key production sites: Elgin, Illinois USA (former DSM Desotech; main global volume plant); Tsukuba, Japan (Japan Fine Coatings, 100% owned, ~65 staff); Zwolle, Netherlands (coating resins). Also a leading polycarbonate and polyurethane supplier for automotive, electronics, and construction — fiber optic coatings are a small but strategically critical business unit.

Huntsman Corporation(HUN)

HQ US14% share

US-based MDI (Rubinate) and polyurethane producer; one of only 4 global commercial-scale MDI producers. Port Neches, TX facility is a primary MDI source for North American OSB mills.
