Korea Kumho Petrochemical
Top global NBR latex supplier (~32% of supply); feedstock for nitrile gloves.
chemical · input
Liquid nitrile butadiene rubber emulsion used as the primary raw material for nitrile examination and surgical gloves. Derived from acrylonitrile and butadiene via emulsion polymerization. Medical-grade NBL is the upstream feedstock for all Malaysian nitrile glove manufacturers (Top Glove, Hartalega, Kossan, Supermax). Approx. 2.5M tons/year global market.

Who makes it
4 companies produce nbr latex (nitrile butadiene rubber latex, medical grade).
Top global NBR latex supplier (~32% of supply); feedstock for nitrile gloves.
Major NBL maker (with Malaysian plants beside glove factories); Kumho + Synthomer ~60% of global NBL.
Zeon Corporation (Tokyo Japan; TSE: 4205; ~¥300B revenue) is the world's largest manufacturer of NBR (nitrile-butadiene rubber) latex for disposable glove production, under the Nippon Zeon brand. Zeon holds an estimated 25-30% global NBR latex market share for glove applications. Primary NBR latex manufacturing at Takaoka plant in Toyama Prefecture, Japan. Zeon's NBR latex is based on the emulsion polymerization of acrylonitrile and butadiene monomers — the same chemistry Nippon Zeon pioneered in Japan in the 1950s. Zeon also produces specialty elastomers (HNBR, chloroprene), optical films (ZEONEX), and medical plastics. The Takaoka facility is the single largest NBR latex production site in Asia outside Malaysia.
