Ueno Fine Chemicals (Japan)

Company Profile

Ueno Fine Chemicals Industry, Ltd.

Founded in 1918 with capital of about JPY 1.01 billion, Ueno Fine Chemicals is a major global supplier of LCP monomer. Building on its leading position in LCP monomers (p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid and others), the company runs integrated monomer-to-resin production, making monomer at its Yokkaichi plant and LCP at its Itami plant, with basic research and technical support from its R&D division. Liquid crystal polymers orient their molecular chains in the melt and show little volume change on solidification, giving high flow, low warpage, high rigidity and a low coefficient of linear thermal expansion. UENO LCP spans the full series from the low-melting 8100 to the high-heat 6000, with halogen-free flame retardancy up to UL-94 V-0, plus low outgassing, high CTI and low loss in the GHz band.
